Description

Technical Field

[0001] This invention relates to the field of service robot technology, specifically to a service robot that is easy to extend, store, and use with a protective screen. Background Technology

[0002] Service robots are autonomous or semi-autonomous intelligent devices applied in non-production fields. They are divided into two categories: professional service robots and personal / household service robots, covering scenarios such as logistics, medical care, security, and housekeeping. According to the definition of the International Federation of Robotics, their technical characteristics include unstructured environmental cognition, multi-sensor information fusion, and human-computer interaction capabilities. The core components involve navigation systems, drive modules, and intelligent control units. Currently, the screens of service robots are usually located on the outside, making it convenient for users to operate the screen to look up the information they need. However, having the screen constantly exposed poses a certain danger. If there are many people around the service robot or children playing nearby, the screen can easily be damaged without the user's knowledge. Summary of the Invention

[0003] The purpose of this invention is to provide a service robot that is easy to extend and store protective screens and is easy to use, so as to solve the problems mentioned in the background art.

[0008] Furthermore, there are two inclined blocks, which are symmetrically arranged around the lifting frame. The two inclined blocks are fixedly connected by a connecting plate, and the inclined surface of the inclined block corresponds to the bottom of the frame.

[0009] Furthermore, the supporting component includes a shaft, the end of which is rotatably connected to the inner wall of the base plate. A positioning plate is fixedly connected to the surface of the shaft, and a force-bearing plate is fixedly connected to the end of the shaft away from the positioning plate. A spring rod is fixedly connected to the bottom of the inner wall of the protective frame, a bearing plate is fixedly connected to the top of the spring rod, a rubber plate is fixedly connected to the top of the bearing plate, a vertical rod is fixedly connected to the bottom of the bearing plate, a pressure frame is fixedly connected to the bottom of the vertical rod, and a compression plate is fixedly connected to the top of the pressure frame. A storage groove is provided at the bottom of the base plate, and a spring piece is fixedly connected to the bottom of the positioning plate. The end of the spring piece away from the positioning plate is fixedly connected to the bottom of the base plate.

[0010] Furthermore, the number of the shafts is set to four, and the four shafts are symmetrically arranged with the base plate as the center. The end of the positioning plate away from the shaft is inclined downward, the end of the force plate away from the shaft is inclined upward, and the bottom of the plumb line penetrates the base plate and extends to the bottom outer end of the base plate.

[0011] Furthermore, the surface of the pressure frame contacts the inner wall of the storage tank, the top of the extrusion plate extends above the bottom plate, the top of the extrusion plate contacts the bottom of the force plate, and there are four extrusion plates, which are arranged in two groups, with two extrusion plates in each group. The two groups of extrusion plates are symmetrically arranged with the protective frame as the center.

[0012] Furthermore, the closing component includes an elastic telescopic rod, the end of which is fixedly connected to the bottom of the bearing plate, a sliding rod fixedly connected to the top of the elastic telescopic rod, a mounting plate fixedly connected to the top of the sliding rod, an inclined plate hinged to the top of the mounting plate, a closing plate hinged to the end of the inclined plate away from the mounting plate, a limit groove formed on the inner wall of the protective frame, a sliding groove formed on the inner wall of the protective frame, and two closing plates located at the ends of the two threaded rods that are close to each other.

[0013] Furthermore, there are two closing plates, which are symmetrically arranged around the bearing plate. The surface of the closing plate is slidably connected to the inner wall of the limiting groove, the surface of the sliding rod is slidably connected to the inner wall of the protective frame, and the lower surface of the sliding rod is slidably connected to the inner wall of the sliding groove.

[0014] The present invention has the following beneficial effects: This invention features casters at the bottom of the base plate, allowing the display to be pushed to the appropriate position for user access. When the display is needed, the drive mechanism is activated. During operation, the drive mechanism, via a pulley and belt, rotates a threaded rod. The lifting frame, as the threaded rod rotates, pushes the stabilizing frame upwards. This movement of the stabilizing frame pushes the display towards the top outer end of the protective frame. Once the stabilizing frame has pushed the display outwards, the user can operate the display to access the required information. To adjust the display height, an electric actuator is activated to extend the display. This actuator pushes the display towards the outer end of the protective frame. At this point, the drive mechanism can be activated to reverse the operation. The threaded rod, as the drive mechanism reverses, pushes the lifting frame downwards. This downward movement of the lifting frame, through the connection between the stabilizing frame and the electric actuator, pushes the display downwards, thus adjusting the display height to accommodate users of different heights and improving the display's service effectiveness.

[0015] When the display needs to be stored inside the protective frame, the electric push rod retracts, pulling the frame towards the surface of the stabilizer. As the frame moves, it pushes the slot to contact the surface of the stabilizer, using the stabilizer to support the frame and improve the stability of the frame supporting the display. When the frame moves towards the surface of the stabilizer, the bottom of the frame contacts the top of the protective pad, and the slope of the inclined block pushes it downward. After the bottom of the frame contacts the protective pad at the top of the inclined block, the inclined block uses the elasticity of the spring rod to squeeze the frame, further improving the stability of the stabilizer supporting the display and preventing the display from shaking and being damaged inside the protective frame.

[0016] In this invention, after the stabilizing frame retracts into the interior of the protective frame, the stabilizing frame continues to move downwards with the operation of the threaded rod. When the top of the stabilizing frame is a certain distance from the top of the inner wall of the protective frame, the bottom of the lifting frame contacts the top of the bearing plate and pushes it downwards. As the bearing plate moves downwards, it pushes the squeezing plate and the force plate to separate through the pressure frame. After separation, the positioning plate uses the elasticity of the spring to reset, so that the operator can push it to move using the casters. When the lifting frame moves upwards, it separates from the bearing plate. During the separation process, the bearing plate moves upwards under the action of the elastic rod. When the bearing plate moves, it pulls the pressure frame upwards through the vertical rod. When the pressure frame moves, it pushes the squeezing plate to squeeze the force plate. After the force plate is subjected to force, it pushes the shaft to rotate. At this time, the shaft pushes the positioning plate to rotate downwards. When the positioning plate rotates downwards, it contacts the ground, thereby using the positioning plate to support and limit the bottom plate, thereby improving the stability of the display during operation.

[0017] When the support plate moves downward, the elastic telescopic rod pulls the slide bar downward. As the slide bar moves downward, it pulls the mounting plate downward. When the mounting plate moves, it pulls the inclined plate, causing deformation. At this time, the inclined plate pushes the closing plate to move towards the outer end of the slide groove. At this time, the two closing plates will contact each other to block the top of the protective frame, preventing heavy objects from falling into the interior of the protective frame and damaging the display. When the support plate moves upward, it first pushes the elastic telescopic rod to retract to its limit. When the support plate continues to move, it pushes the slide bar upward through the elastic telescopic rod. When the slide bar moves, it pushes the inclined plate through the mounting plate. The inclined plate pushes the closing plate into the interior of the slide groove, thereby separating the two closing plates so that the display can move to the outer end of the protective frame to serve the user.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 As shown, the present invention is a service robot that is easy to extend, store and use with a protective screen. It includes a base plate 4, a universal wheel 5 rotatably connected to the bottom of the base plate 4, a protective frame 1 fixedly connected to the top of the base plate 4, a frame 2 provided on the surface of the protective frame 1, a display 3 provided inside the frame 2, and a lifting component 6 provided inside the protective frame 1. The lifting component 6 includes a threaded rod 20, the surface of which is rotatably connected to the inner wall of the protective frame 1. A drive device 24 is fixedly connected to the inner wall of the protective frame 1. A pulley 22 is fixedly connected to the output end of the drive device 24 and the bottom of the threaded rod 20, respectively. A belt 23 is driven through the inner wall of the pulley 22. A lifting frame 25 is threadedly connected to the surface of the threaded rod 20. A stabilizing frame 26 is fixedly connected to the top of the lifting frame 25. An electric push rod 28 is fixedly connected to the upper surface of the stabilizing frame 26. A slot 27 is provided at the end of the frame 2 away from the display 3. The end of the electric push rod 28 away from the stabilizing frame 26 is fixedly connected to the inner wall of the frame 2. When the drive device 24 is in operation, it drives the threaded rod 20 to rotate through the connection between the pulley 22 and the belt 23. As the threaded rod 20 rotates, the lifting frame 25 pushes the stabilizing frame 26 upward. 6. When moving, the display 3 will be pushed to the top outer end of the protective frame 1. After the stabilizer 26 pushes the display 3 out of the top outer end of the protective frame 1, the user can operate the display 3 to query the required information. When the height of the display 3 needs to be adjusted, the electric push rod 28 is activated to start the extension operation. When the electric push rod 28 is working, it will push the display 3 to the outer end of the protective frame 1. At this time, the drive device 24 can be activated to start the reverse operation. The threaded rod 20 pushes the lifting frame 25 downward as the drive device 24 reverses. When the lifting frame 25 moves downward, it pushes the display 3 downward through the connection between the stabilizer 26 and the electric push rod 28, thereby adjusting the height of the display 3. The top of the lifting frame 25 is provided with a stabilizing component 7, the surface of the base plate 4 is provided with a supporting component 8, and the inside of the protective frame 1 is provided with a closing component 9.

[0024] There are two threaded rods 20, which are symmetrically arranged with the protective frame 1 as the center. The bottom of the threaded rod 20 passes through the protective frame 1 and extends to the bottom outer end of the protective frame 1. The bottom of the threaded rod 20 is rotatably connected to the top of the base plate 4, and the top of the threaded rod 20 extends to the top outer end of the protective frame 1. The belt 23 is arranged in a triangle.

[0025] The lifting frame 25 is located inside the protective frame 1. The surface of the stabilizing frame 26 is adapted to the inner wall of the slot 27. The bottom of the electric push rod 28 contacts the top of the protective frame 1. The end of the electric push rod 28 away from the frame 2 extends into the interior of the stabilizing frame 26. The end of the electric push rod 28 near the stabilizing frame 26 is adapted to the inner wall of the frame 2.

[0026] The stabilizing component 7 includes a spring rod 31. The bottom of the spring rod 31 is fixedly connected to the top of the lifting frame 25. A ramp block 33 is fixedly connected to the top of the spring rod 31. A protective pad 30 is fixedly connected to the top of the ramp block 33. A connecting plate 32 is fixedly connected to the end of the ramp block 33. When the monitor 3 needs to be stored inside the protective frame 1, the electric push rod 28 begins to retract, which pulls the frame 2 towards the surface of the stabilizing frame 26. As the frame 2 moves, it pushes the slot 27 to contact the surface of the stabilizing frame 26, using the stabilizing frame 26 to support the frame 2 and improve the stability of the frame 2 in supporting the monitor 3. When the frame 2 moves towards the surface of the stabilizing frame 26, the bottom of the frame 2 contacts the top of the protective pad 30, and the ramp block 33 pushes it downward. After the bottom of the frame 2 contacts the protective pad 30 at the top of the ramp block 33, the ramp block 33 uses the elasticity of the spring rod 31 to squeeze the frame 2, further improving the stability of the stabilizing frame 26 in supporting the monitor 3.

[0027] There are two inclined blocks 33. The two inclined blocks 33 are symmetrically arranged with the lifting frame 25 as the center. The two inclined blocks 33 are fixedly connected by the connecting plate 32. The inclined surface of the inclined block 33 corresponds to the bottom of the frame 2.

[0028] The support component 8 includes a shaft 42, the end of which is rotatably connected to the inner wall of the base plate 4. A positioning plate 46 is fixedly connected to the surface of the shaft 42. A force-bearing plate 45 is fixedly connected to the end of the shaft 42 away from the positioning plate 46. A spring rod 47 is fixedly connected to the bottom of the inner wall of the protective frame 1. A bearing plate 40 is fixedly connected to the top of the spring rod 47. A rubber plate 41 is fixedly connected to the top of the bearing plate 40. A vertical rod 48 is fixedly connected to the bottom of the bearing plate 40. A pressure frame 43 is fixedly connected to the bottom of the vertical rod 48. A compression plate 44 is fixedly connected to the top of the pressure frame 43. A storage groove 50 is provided at the bottom of the base plate 4. A spring piece 49 is fixedly connected to the bottom of the positioning plate 46. The end of the spring piece 49 away from the positioning plate 46 is fixedly connected to the bottom of the base plate 4. When the stabilizer 26 retracts into the interior of the protective frame 1, the stabilizer 26 continues to move downward with the operation of the threaded rod 20. When the top of the stabilizer 26 is in contact with the protective frame 1... After a certain distance from the top of the inner wall, the bottom of the lifting frame 25 will contact the top of the bearing plate 40 and push it downward. When the bearing plate 40 moves downward, it will push the squeezing plate 44 and the force plate 45 to separate through the pressure frame 43. After separation, the positioning plate 46 will be reset by the elasticity of the spring piece 49 so that the operator can push it to move through the caster wheel 5. When the lifting frame 25 moves upward, it will separate from the bearing plate 40. During the separation process, the bearing plate 40 moves upward under the action of the spring rod 47. When the bearing plate 40 moves, it will pull the pressure frame 43 upward through the vertical rod 48. When the pressure frame 43 moves, it will push the squeezing plate 44 to squeeze the force plate 45. After the force plate 45 is subjected to force, it will push the shaft 42 to rotate. At this time, the shaft 42 will push the positioning plate 46 to rotate downward. When the positioning plate 46 rotates downward, it will contact the ground, thereby using the positioning plate 46 to support and limit the bottom plate 4.

[0029] There are four shafts 42, which are symmetrically arranged around the base plate 4. The end of the positioning plate 46 away from the shaft 42 is inclined downward, and the end of the force plate 45 away from the shaft 42 is inclined upward. The bottom of the vertical rod 48 passes through the base plate 4 and extends to the bottom outer end of the base plate 4.

[0030] The surface of the pressure frame 43 contacts the inner wall of the storage tank 50. The top of the extrusion plate 44 extends above the bottom plate 4. The top of the extrusion plate 44 contacts the bottom of the force plate 45. There are four extrusion plates 44. The four extrusion plates 44 are set in two groups, and each group has two extrusion plates. The two groups of extrusion plates 44 are symmetrically arranged with the protective frame 1 as the center.

[0031] The closing component 9 includes an elastic telescopic rod 63. The end of the elastic telescopic rod 63 is fixedly connected to the bottom of the support plate 40. A sliding rod 64 is fixedly connected to the top of the elastic telescopic rod 63. A mounting plate 65 is fixedly connected to the top of the sliding rod 64. An inclined plate 66 is hinged to the top of the mounting plate 65. A closing plate 61 is hinged to the end of the inclined plate 66 away from the mounting plate 65. A limit groove 60 and a sliding groove 62 are provided on the inner wall of the protective frame 1. When the support plate 40 moves downward, the elastic telescopic rod 63 pulls the sliding rod 64 downward. When the sliding rod 64 moves downward, it pulls the mounting plate 65 downward. During this movement, the mounting plate 65 deforms by pulling the inclined plate 66. The inclined plate 66 pushes the closing plate 61 to move towards the outer end of the slide 62. At this time, the two closing plates 61 will contact each other to block the top of the protective frame 1, preventing heavy objects from falling into the interior of the protective frame 1 and damaging the display 3. When the support plate 40 moves upward, it will first push the elastic telescopic rod 63 to retract to its limit. When the support plate 40 continues to move, it will push the slide rod 64 upward through the elastic telescopic rod 63. When the slide rod 64 moves, it pushes the inclined plate 66 to move through the mounting plate 65. The inclined plate 66 pushes the closing plate 61 into the interior of the slide 62, thereby separating the two closing plates 61 so that the display 3 can move to the outer end of the protective frame 1 to serve the user.

[0032] There are two closing plates 61, which are symmetrically arranged with the bearing plate 40 as the center. The surface of the closing plate 61 is slidably connected to the inner wall of the limiting groove 60, the surface of the slide rod 64 is slidably connected to the inner wall of the protective frame 1, and the lower surface of the slide rod 64 is slidably connected to the inner wall of the slide groove 62.

[0033] In use, casters 5 are installed at the bottom of the base plate 4 to push the monitor 3 to the corresponding position for use. When the monitor 3 is needed, the drive device 24 is started. During operation, the drive device 24 drives the threaded rod 20 to rotate through the connection between the pulley 22 and the belt 23. As the threaded rod 20 rotates, the lifting frame 25 pushes the stabilizing frame 26 upward. When the stabilizing frame 26 moves, it pushes the monitor 3 towards the top outer end of the protective frame 1. After the stabilizing frame 26 pushes the monitor 3 out of the top outer end of the protective frame 1, the user can operate the monitor. When the display 3 queries the required information and the height of the display 3 needs to be adjusted, the electric actuator 28 is activated to start the extension operation. During operation, the electric actuator 28 will push the display 3 to move towards the outer end of the protective frame 1. At this time, the drive device 24 can be activated to start the reverse operation. The threaded rod 20 pushes the lifting frame 25 downward as the drive device 24 reverses. When the lifting frame 25 moves downward, it pushes the display 3 downward through the connection between the stabilizer 26 and the electric actuator 28, thereby adjusting the height of the display 3 so that the display 3 can adapt to users of different heights and improve the service effect of the display 3. When the monitor 3 needs to be stored inside the protective frame 1, the electric push rod 28 begins to retract, pulling the frame 2 towards the surface of the stabilizer 26. As the frame 2 moves, it pushes the slot 27 to contact the surface of the stabilizer 26, using the stabilizer 26 to support the frame 2 and improve the stability of the frame 2 in supporting the monitor 3. When the frame 2 moves towards the surface of the stabilizer 26, the bottom of the frame 2 will contact the top of the protective pad 30, and the slope of the inclined block 33 will push it downward. When the bottom of the frame 2 contacts the protective pad 30 on the top of the inclined block 33, the inclined block 33 will use the elasticity of the spring rod 31 to squeeze the frame 2, further improving the stability of the stabilizer 26 in supporting the monitor 3 and preventing the monitor 3 from shaking and being damaged inside the protective frame 1. After the stabilizer 26 retracts into the interior of the protective frame 1, it continues to move downwards with the operation of the threaded rod 20. When the top of the stabilizer 26 is a certain distance from the top of the inner wall of the protective frame 1, the bottom of the lifting frame 25 contacts the top of the bearing plate 40 and pushes it downwards. As the bearing plate 40 moves downwards, it pushes the pressing plate 44 and the force plate 45 apart through the pressure frame 43. After separation, the positioning plate 46 is reset by the elasticity of the spring 49, so that the operator can push it to move using the casters 5. When the lifting frame 25 moves upwards, the lifting... The lowering frame 25 will separate from the bearing plate 40. During the separation process, the bearing plate 40 moves upward under the action of the elastic rod 47. When the bearing plate 40 moves, it pulls the pressure frame 43 upward through the vertical rod 48. When the pressure frame 43 moves, it pushes the extrusion plate 44 to extrude the force plate 45. After the force plate 45 is subjected to force, it pushes the shaft 42 to rotate. At this time, the shaft 42 will push the positioning plate 46 to rotate downward. When the positioning plate 46 rotates downward, it will contact the ground, thereby using the positioning plate 46 to support and limit the bottom plate 4, thereby improving the stability of the display 3 during operation. When the support plate 40 moves downward, it pulls the slide bar 64 downward through the elastic telescopic rod 63. When the slide bar 64 moves downward, it pulls the mounting plate 65 downward. When the mounting plate 65 moves, it pulls the inclined plate 66 to deform. At this time, the inclined plate 66 pushes the closing plate 61 to move towards the outer end of the slide groove 62. At this time, the two closing plates 61 will contact each other to block the top of the protective frame 1 and prevent heavy objects from falling into the interior of the protective frame 1 and damaging the display 3. When the support plate 40 moves upward, it first pushes the elastic telescopic rod 63 to retract to its limit. When the support plate 40 continues to move, it pushes the slide bar 64 upward through the elastic telescopic rod 63. When the slide bar 64 moves, it pushes the inclined plate 66 to move through the mounting plate 65. The inclined plate 66 pushes the closing plate 61 into the interior of the slide groove 62, so that the two closing plates 61 separate from each other, so that the display 3 can move to the outer end of the protective frame 1 to serve the user.
