Description

Technical Field

[0001] The present invention relates to the technical field of robots, and particularly to an adjustable-height combined intelligent robot. Background Art

[0002] A combined intelligent robot refers to a robot system that integrates various advanced technologies (such as artificial intelligence, Internet of Things, robotics, big data, etc.) and functional modules to achieve high intelligence and multi-functional collaboration. For example, robots for intelligent transportation (delivering meals, items, etc.) in hotels or restaurants.

[0003] During the process of a transportation robot transporting items (food, takeaways, daily necessities, etc.), in order to make it easier to place and pick up items above the placement board inside the robot, the placement board is usually set at a certain height. However, this will cause the balance center of gravity of the transportation robot to be relatively high. During the movement of the transportation robot, this high-center-of-gravity design will limit the movement speed of the transportation robot, limit the transportation efficiency of the transportation robot, and increase the waiting time of customers. Summary of the Invention

[0004] Technical Problem to be Solved In view of the above-mentioned drawbacks of the prior art, the present invention provides an adjustable-height combined intelligent robot, which can effectively solve the problem that in the prior art, during the process of a transportation robot transporting items, in order to make it easier to place and pick up items above the placement board inside the robot, the placement board is usually set at a certain height, but this will cause the balance center of gravity of the transportation robot to be relatively high. During the movement of the transportation robot, this high-center-of-gravity design will limit the movement speed of the transportation robot, limit the transportation efficiency of the transportation robot, and increase the waiting time of customers.

[0005] Technical Solution To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides an adjustable-height combined intelligent robot, including a cylindrical outer shell and a driving component at the bottom of the outer shell. A placement opening is provided on one side of the outer shell. The driving component includes a lifting plate installed below the inner part of the outer shell. A lifting frame is fixedly installed below the lifting plate, and a driving wheel is drivingly installed below the lifting frame; A placement board is slidably installed up and down inside the outer shell. The placement board is used to hold items to be transported. The placement board is located on one side of the placement opening. A sealing board is slidably installed up and down at the placement opening. The sealing board is used to block the placement opening. A telescopic member for driving the sealing board to move up and down is fixedly installed inside the outer shell. An adjusting component for adjusting the up and down position of the placement board is provided inside the outer shell.

[0006] Furthermore, a fixing plate is fixedly installed inside the outer shell. The fixing plate is located below the placing plate. The telescopic member is fixedly installed on the fixing plate. A supporting plate is arranged on the side surface of the sealing plate. One end of the supporting plate away from the sealing plate extends to the middle part below the placing plate.

[0007] Furthermore, the adjusting assembly includes four connecting rods distributed in a rhombus shape. After the supporting plate moves upward, it drives the adjusting assembly to adjust the placing plate to move downward. After the supporting plate moves downward, the adjusting assembly automatically drives the placing plate to move upward.

[0008] Furthermore, one ends of the two upper connecting rods close to each other are rotatably connected to the placing plate. The other ends of the two upper connecting rods are horizontally slidably and rotatably connected to the inner wall of the outer shell. The two lower connecting rods are symmetrically distributed with the two upper connecting rods. One ends of the two connecting rods on the same side are synchronously slidably installed on the inner wall of the outer shell. After the supporting plate moves upward, it drives one ends of the two lower connecting rods close to each other to move upward; an elastic member for driving the two ends of the two connecting rods away from each other to approach each other is arranged in the middle of the two upper connecting rods.

[0009] Furthermore, a guiding block is fixedly installed on the inner wall of the outer shell. A guiding chute for guiding the horizontal sliding of the rotating connecting rod at one end of the connecting rod is arranged on the guiding block. The rotating connecting rods of the two connecting rods on the same side slide synchronously inside the guiding chute.

[0010] Furthermore, a screw rod is rotatably installed below the fixing plate. The lower end of the screw rod passes through the lifting plate and is threadedly connected to the lifting plate. A driving motor for driving the screw rod to rotate is arranged on the fixing plate. By driving the screw rod to rotate, the driving motor drives the lifting plate to move up and down.

[0011] Furthermore, two guide rails are symmetrically installed inside the outer shell. The two guide rails are respectively located on both sides of the placing opening. The two guide rails are used for guiding the up and down movement of the sealing plate.

[0012] Furthermore, a first partition plate is fixedly installed below the placing plate. A second partition plate is fixedly installed on the fixing plate. The first partition plate and the second partition plate are staggered and closely attached to each other. An installation cylinder is arranged on the second partition plate. The other end of the installation cylinder is communicated with an air exhaust port arranged on the outer shell. An air exhaust assembly is arranged inside the installation cylinder.

[0013] Furthermore, the air exhaust assembly includes a spiral fan blade rotatably installed inside the installation cylinder. A tooth row is fixedly installed below the first partition plate. A transmission member is also arranged on the second partition plate. The transmission member is used for driving the spiral fan blade to rotate under the drive of the tooth row.

[0014] Beneficial effects The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies: 1. In the present invention, by arranging a placement plate inside the outer shell and opening a placement opening at the outer shell on the side of the placement plate, after placing an item inside the placement plate, by driving the telescopic member to extend, the sealing plate can be driven to slide upward to close the placement opening. At the same time, after the sealing plate moves upward, by driving the adjustment assembly, the placement plate can be driven to move downward, so that the placement plate and the items on the placement plate are moved to a lower position, reducing the overall center of gravity of the robot. When the robot is in motion, it can reach a faster speed while ensuring the stability of the items, thereby improving the conveying efficiency of the robot.

[0015] 2. In the present invention, by arranging four link rods distributed in a diamond shape on the inner wall of the outer shell below the placement plate, when the support plate moves upward following the telescopic member to the position where the lower ends of the two lower link rods approach each other, as the support plate continues to move upward, it will drive the lower ends of the two lower link rods to move upward, and then drive the lower ends of the two upper link rods to move downward, causing the placement plate located above the link rods to move downward; using the upward movement of the sealing plate to close the placement opening to synchronously drive the placement plate to move downward can synchronously and coherently achieve the purpose of reducing the overall center of gravity of the robot.

[0016] 3. In the present invention, by respectively arranging a first partition plate below the placement plate and a second partition plate above the fixed plate, during the lifting process of the placement plate, the mutually staggered and closely attached first partition plate and second partition plate can limit the air outside the outer shell from entering the inner part of the outer shell through the air outlet. By arranging an installation cylinder on the second partition plate and a spiral fan blade inside the installation cylinder, and at the same time arranging a tooth row and a transmission member, when the placement plate moves downward, it will drive the tooth row to move downward synchronously. At this time, the tooth row will drive the transmission member to drive the spiral fan blade to rotate, and discharge the air inside the outer shell from the air outlet, preventing the smell of the conveyed items from remaining inside the outer shell.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] For this reason, the embodiments of the present invention provide an adjustable-height combined intelligent robot, the purpose of which is at least to drive the placing plate 11 to move downward, so that the placing plate 11 and the items on the placing plate 11 are moved to a lower position, reducing the overall center of gravity of the robot, enabling the robot to reach a faster speed while ensuring the stability of the items during movement, and improving the conveying efficiency of the robot.

[0023] Embodiment: An adjustable-height combined intelligent robot, as Figure 1 - Figure 4As shown in the figure, it includes a cylindrical outer shell 1 and a driving component 2 at the bottom of the outer shell 1. One side of the outer shell 1 is provided with a placement opening 101. The driving component 2 includes a lifting plate 13 installed below the interior of the outer shell 1. A lifting frame 22 is fixedly installed below the lifting plate 13, and a driving wheel 21 is drivingly installed below the lifting frame 22; A placement plate 11 is slidably installed up and down inside the outer shell 1. The placement plate 11 is used to hold the items to be transported. The placement plate 11 is located on one side of the placement opening 101. A sealing plate 15 is slidably installed up and down at the placement opening 101. The sealing plate 15 is used to block the placement opening 101. A telescopic member 121 for driving the sealing plate 15 to move up and down is fixedly installed inside the outer shell 1. An adjusting component 3 for adjusting the up and down position of the placement plate 11 is provided inside the outer shell 1.

[0024] In the present invention, by providing a placement plate 11 inside the outer shell 1 and opening a placement opening 101 at the outer shell 1 on the side of the placement plate 11, after the items are placed inside the placement plate 11, by driving the telescopic member 121 to extend, the sealing plate 15 can be driven to slide upward to close the placement opening 101. At the same time, after the sealing plate 15 moves upward, by driving the adjusting component 3, the placement plate 11 can be driven to move downward, so that the placement plate 11 and the items on the placement plate 11 are moved to a lower position, reducing the overall center of gravity of the robot. When the robot is moving, it can reach a faster speed while ensuring the stability of the items, which can improve the conveying efficiency of the robot.

[0025] Furthermore, as Figure 4 and Figure 5 shown, a fixing plate 12 is fixedly installed inside the outer shell 1. The fixing plate 12 is located below the placement plate 11. The telescopic member 121 is fixedly installed on the fixing plate 12. A support plate 151 is provided on the side of the sealing plate 15. One end of the support plate 151 away from the sealing plate 15 extends to the middle below the placement plate 11.

[0026] Among them, by fixedly installing the fixing plate 12 inside the outer shell 1, the telescopic member 121 can be stably supported. The telescopic member 121 is connected to the lower part of the support plate 151 on the side of the sealing plate 15. The sealing plate 15 can be stably driven to move up and down by the telescopic member 121.

[0027] Furthermore, as Figure 5 and Figure 6As shown in the figure, the adjusting assembly 3 includes four link rods 31 distributed in a rhombus shape. After the support plate 151 moves upward, it drives the adjusting assembly 3 to adjust the placing plate 11 to move downward. After the support plate 151 moves downward, the adjusting assembly 3 automatically drives the placing plate 11 to move upward. One ends of the two upper link rods 31 close to each other are rotatably connected to the placing plate 11, and the other ends of the two upper link rods 31 are horizontally slidably and rotatably connected to the inner wall of the housing 1. The two lower link rods 31 are symmetrically distributed with the two upper link rods 31. One ends of the two link rods 31 on the same side are synchronously slidably mounted on the inner wall of the housing 1. After the support plate 151 moves upward, it drives one ends of the two lower link rods 31 close to each other to move upward. An elastic member 32 for driving the two ends of the two link rods 31 away from each other to approach each other is provided in the middle of the two upper link rods 31.

[0028] Among them, by arranging four link rods 31 distributed in a rhombus shape on the inner wall of the housing 1 below the placing plate 11, when the support plate 151 moves upward following the telescopic member 121 to the position where one ends of the two lower link rods 31 close to each other, as the support plate 151 continues to move upward, it will drive one ends of the two lower link rods 31 close to each other to move upward, and further drive one ends of the two upper link rods 31 close to each other to move downward, so that the placing plate 11 located above the link rods 31 moves downward. Utilizing the upward movement of the sealing plate 15 to close the placing opening 101 to synchronously drive the placing plate 11 to move downward can synchronously and coherently achieve the purpose of lowering the overall center of gravity of the robot.

[0029] In addition, during the process of driving the sealing plate 15 to move downward by the telescopic member 121 to open the placing opening 101, the elastic member 32 will drive the two upper or two lower link rods 31 on the left and right sides to approach each other, so that the upper and lower ends of the adjusting assembly 3 move away from each other, and then the placing plate 11 moves upward smoothly, making it more convenient for customers to take items from the placing opening 101. A support block 312 is provided below the placing plate 11, and the lower ends of the support block 312 are respectively rotatably connected to the left and right link rods 31.

[0030] Further, as Figure 6 shown, a guiding block 16 is fixedly mounted on the inner wall of the housing 1. A guiding chute for guiding the horizontal sliding of the rotating connecting rod 311 at one end of the link rod 31 is provided on the guiding block 16. The rotating connecting rods 311 of the two link rods 31 on the same side slide synchronously inside the guiding chute.

[0031] Among them, by fixedly mounting the guiding block 16 on the inner wall of the housing 1, the guiding block 16 can conveniently guide the two link rods 31 on the same side (both on the left side or the right side) close to each other to move horizontally synchronously, making the movement of the placing plate 11 more stable.

[0032] Further, asFigure 5 As shown, a screw rod 131 is rotatably installed under the fixed plate 12, and the lower end of the screw rod 131 passes through the lifting plate 13 and is threadedly connected to the lifting plate 13. A driving motor 132 for driving the screw rod 131 to rotate is provided on the fixed plate 12, and a bevel gear set is provided on the screw rod 131. The driving motor 132 is transmission-connected to the screw rod 131 through the bevel gear set. The driving motor 132 drives the screw rod 131 to rotate, thereby driving the lifting plate 13 to move up and down.

[0033] Among them, by rotating the screw 131 installed on the fixed plate 12 and setting a driving motor 132 on the side of the screw 131, when taking and placing items, the driving motor 132 drives the screw 131 to rotate so that the lifting plate 13 can move downward relative to the shell 1, which can further increase the height of the placement opening 101, making it more convenient for staff or customers to take and place items from the placement opening 101.

[0034] Furthermore, if Figure 3 and Figure 4 As shown, two guide rails 14 are symmetrically installed inside the shell 1, and the two guide rails 14 are respectively located on both sides of the placement opening 101. The two guide rails 14 are used to guide the sealing plate 15 to move up and down, and can stably guide the sealing plate 15 to move up and down. A groove for guiding the movement of the sealing plate 15 is arranged on the guide rail 14, and a sealing gasket is arranged inside the groove.

[0035] Furthermore, if Figure 7 As shown, a first partition 111 is fixedly installed below the placement plate 11, and a second partition 122 is fixedly installed on the fixed plate 12. The first partition 111 and the second partition 122 are staggered and close to each other, and a mounting tube 1201 is provided on the second partition 122. The other end of the mounting tube 1201 is connected to the exhaust port 102 provided on the outer shell 1, and an exhaust assembly is provided in the mounting tube 1201; the exhaust assembly includes a spiral fan blade 123 rotatably installed inside the mounting tube 1201, a tooth row 112 is fixedly installed below the first partition 111, and a transmission member 124 is also provided on the second partition 122. The transmission member 124 is used to drive the spiral fan blade 123 to rotate under the drive of the tooth row 112.

[0036] Among them, by respectively arranging the first partition 111 and the second partition 122 below the placement plate 11 and above the fixed plate 12, during the lifting and lowering process of the placement plate 11, the first partition 111 and the second partition 122 that are staggered and tightly attached to each other can limit the air outside the outer shell 1 from the exhaust port 102 to the inside of the outer shell 1, and by arranging the installation cylinder 1201 on the second partition 122 and arranging the spiral fan blades 123 inside the installation cylinder 1201, and arranging the tooth row 112 and the transmission member 124 at the same time, during the downward movement of the placement plate 11, the tooth row 112 will be driven to move downward synchronously. At this time, the tooth row 112 will drive the transmission member 124 to drive the spiral fan blades 123 to rotate, so that the air inside the outer shell 1 is discharged outward from the exhaust port 102, thereby preventing the smell of the transported items from being retained inside the outer shell 1.

[0037] In addition, the transmission member 124 specifically includes a coaxially arranged gear and a pulley, the gear is used to mesh with the tooth row 112, and another set of pulleys is coaxially arranged on the spiral blade 123, and the two sets of pulleys are mutually driven by belts.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
