[0002] With the development of big data, cloud computing and artificial intelligence (AI), the frequency of installation and debugging of computing devices is increasing, and computing devices need to be frequently mounted in or removed from a cabinet.

[0003] The computing devices can be mounted and removed by an operation and maintenance robot. The operation and maintenance robot includes a robot body and a plugging mechanism. The robot body has wheels at the bottom, which can drive the robot body to move to the cabinet, and the plugging mechanism moves to align with a corresponding slot in the cabinet, and then the plugging mechanism clamps the computing device to mount the computing device in the cabinet or remove the computing device from the cabinet. However, it is difficult for the operation and maintenance robot to mount or remove the computing device located at the bottom of the cabinet. UTILITY MODEL CONTENT

[0004] Embodiments of the present application provide an operation and maintenance robot, and the plugging mechanism in the operation and maintenance robot can conveniently plug and unplug the computing device located in the slot at the lowermost layer of the cabinet.

[0005] In a first aspect, embodiments of the present application provide an operation and maintenance robot, which includes a robot body, a support frame, a moving part and a plugging mechanism. The support frame is connected to the bottom end of the robot body, and the support frame has a receiving groove recessed in a direction away from the robot body. The moving part is connected to the support frame and is arranged on both sides of the receiving groove in a first direction. The projection of the moving part in the first direction at least partially overlaps the projection of the receiving groove in the first direction. The distance from the moving part away from the robot body to the bottom end of the robot body is greater than the distance from the receiving groove away from the robot body to the bottom end of the robot body. The plugging mechanism is connected to the robot body, and the plugging mechanism can move in a second direction to be located in the receiving groove.

[0006] The operation and maintenance robot provided by embodiments of the present application has the following advantages. The robot body, the support frame, the moving part and the plugging mechanism are arranged. The support frame is connected to the bottom end of the robot body, and the support frame has a receiving groove recessed in a direction away from the robot body. The moving part is connected to the support frame and is arranged on both sides of the receiving groove in a first direction. The projection of the moving part in the first direction at least partially overlaps the projection of the receiving groove in the first direction, so that the distance from the bottom surface of the receiving groove to the support surface is small. The plugging mechanism is connected to the robot body and can move in a second direction to be located in the receiving groove, so that the distance from the plugging mechanism to the support surface is also small. Therefore, the plugging mechanism can conveniently plug and unplug the computing device located in the slot at the lowermost layer of the cabinet.

[0057] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0058] With the development of big data, cloud computing and artificial intelligence (AI), the installation and debugging of computing devices are becoming more and more frequent, and computing devices need to be frequently mounted in or removed from the cabinet.

[0059] Figure 1 is a structural schematic diagram of a data center; Figure 2 is a structural schematic diagram of a computing device mounted on a cabinet.

[0060] Referring to Figure 1 and Figure 2 , the data center 1000 can include a machine room (not labeled in the figure) and a plurality of cabinets 20 and a plurality of computing devices 30 arranged in the machine room.

[0061] The cabinet 20 serves as a support component for the computing device 30. Please continue to refer to Figure 2 , the cabinet 20 has a first direction X, a second direction Y and a third direction Z, wherein the first direction X can be the width direction of the cabinet 20, the second direction Y can be the height direction of the cabinet 20, and the third direction Z can be the depth direction of the cabinet. The cabinet 20 has a plurality of slot positions arranged along the second direction Y, each slot position 21 can be used to mount a computing device 30, and a plurality of computing devices 30 are arranged along the second direction Y. Figure 2 The slot position 21 at the lowermost layer along the height direction of the cabinet is schematically shown by a dashed line in

[0062] The computing device 30 can be manually carried and mounted in or removed from the cabinet 20. Please continue to refer to Figure 1 , the machine room is also provided with a maintenance robot 10, which can move in the channel formed by the adjacent two rows of cabinets 20 to move the computing device 30 to the vicinity of the cabinet 20. The computing device 30 can also be mounted in or removed from the cabinet 20.

[0063] Figure 3 is a structural schematic diagram of a maintenance robot provided by an embodiment of the present application; Figure 4 is a process schematic diagram of a maintenance robot carrying a computing device provided by an embodiment of the present application; Figure 5 is a process schematic diagram of a maintenance robot mounting or removing a computing device provided by an embodiment of the present application; and Figure 7Another structural schematic diagram of the support frame and the moving part in the operation and maintenance robot provided by the embodiment of the present application is shown in the figure, wherein, Figure 7 The ground G is also schematically shown in the figure.

[0064] Referring to Figures 3 to 7 As shown in the figure, the operation and maintenance robot 10 provided by the embodiment of the present application comprises a robot body 100, a support frame 200, a moving part 300 and a plugging mechanism 400. The support frame 200 is connected to the bottom end of the robot body 100, and the support frame 200 has a containing groove 210 recessed away from the robot body 100. The moving part 300 is connected to the support frame 200, and the moving part 300 is arranged on both sides of the containing groove 210 along the first direction X. The projection of the moving part 300 along the first direction X at least partially coincides with the projection of the containing groove 210 along the first direction X. The distance from the side of the moving part 300 away from the robot body 100 to the bottom end of the robot body 100 is greater than the distance from the side of the containing groove 210 away from the robot body to the bottom end of the robot body 100. The plugging mechanism 400 is connected to the robot body 100, and the plugging mechanism 400 can be moved along the second direction Y to be located in the containing groove 210.

[0065] Please continue to refer to Figures 3 to 5 As shown in the figure, the operation and maintenance robot 10 comprises a robot body 100. The first direction X, the second direction Y and the third direction Z of the operation and maintenance robot 10 are the same as the first direction X, the second direction Y and the third direction Z of the cabinet 20.

[0066] The robot body 100 is used to support the plugging mechanism 400. Specifically, the robot body 100 comprises two side plates 110 arranged oppositely along the first direction X. The side plates 110 have slide rails 120 extending along the second direction Y. The plugging mechanism 400 is connected to the slide rails 120 and can be moved along the second direction Y on the slide rails 120. For example, the plugging mechanism 400 can be moved along the second direction Y to be aligned with one of the slot positions 21 in the cabinet 20. When the computing device 30 is located on the plugging mechanism 400, the plugging mechanism 400 clamps the computing device 30 and pushes the computing device 30 along the third direction Z towards the cabinet 20 to rack the computing device 30 into the cabinet 20. When the computing device 30 is to be un-racked, the plugging mechanism 400 clamps the computing device 30 and pulls the computing device 30 along the third direction Z to move the computing device 30 away from the cabinet 20 to un-rack the computing device 30 from the cabinet 20.

[0067] The support frame 200 is arranged at the bottom end of the robot body 100 along the second direction Y. The support frame 200 is used to support the robot body 100 and the plugging mechanism 400 located on the robot body 100. The support frame 200 is also used to connect the moving part 300 to the robot body 100.

[0068] The support surface can be the ground G in the machine room, or can be another support surface for supporting and moving the maintenance robot 10. In the embodiments of the present application, the ground G in the machine room is taken as an example for description.

[0069] The specific structure of the support frame 200 and the relative position between the support frame 200 and the moving part 300 will be described below.

[0070] Please continue to refer to Figure 6 and Figure 7 As shown in FIG. 4, the support frame 200 is provided with a receiving groove 210 recessed towards the ground G. The receiving groove 210 can be aligned with the plug-in mechanism 400 along the second direction Y, and the size of the receiving groove 210 along the first direction X is greater than the size of the plug-in mechanism 400 along the first direction X, and the size of the receiving groove 210 along the third direction Z is greater than the size of the plug-in mechanism 400 along the third direction Z.

[0071] The moving part 300 is arranged on both sides of the receiving groove 210 along the first direction X, and can drive the robot body 100 to move, so as to move the robot body 100 to different cabinet bodies 20. The moving part 300 can be a universal wheel or a track.

[0072] Please continue to refer to Figure 7 As shown in FIG. 4, one end of the moving part 300 along the second direction Y is in contact with the ground G, and the other end can be connected with the support frame 200. The projection of the receiving groove 210 along the first direction X is a first projection S1 (shown schematically in FIG. 4), and the projection of the moving part 300 along the first direction X is a second projection S2 (shown schematically in FIG. 4). The second projection S2 at least partially overlaps the first projection S1, that is, the moving part 300 and the receiving groove 210 at least partially overlap along the second direction Y. Therefore, the distance between the bottom surface of the receiving groove 210 and the ground G can be set smaller. Figure 7 Figure 7 It should be noted that the distance from the side of the moving part 300 away from the robot body 100 to the bottom end of the robot body 100 is greater than the distance from the side of the receiving groove 210 away from the robot body 100 to the bottom end of the robot body 100. Therefore, the side of the receiving groove 210 away from the robot body 100 can be prevented from contacting the ground G and hindering the movement of the maintenance robot 10.

[0073] It should be noted that the distance from the side of the moving part 300 away from the robot body 100 to the bottom end of the robot body 100 is greater than the distance from the side of the receiving groove 210 away from the robot body 100 to the bottom end of the robot body 100. Therefore, the side of the receiving groove 210 away from the robot body 100 can be prevented from contacting the ground G and hindering the movement of the maintenance robot 10.

[0074] Please continue to refer to Figure 5 As shown in FIG. 4, the plug-in mechanism 400 can be moved into the receiving groove 210 along the second direction Y (shown schematically in FIG. 4). Figure 5 ​When the plug-pull mechanism 400 is in the position shown by the dashed line (i.e., another position of the plug-pull mechanism 400 along the second direction Y), the distance between the plug-pull mechanism 400 and the ground G is also small, so that the plug-pull mechanism 400 can conveniently plug and pull the computing device 30 located in the slot 21 of the lowermost layer of the cabinet 20.

[0075] The operation and maintenance robot 10 provided by the embodiment of the present application is provided with the robot body 100, the support frame 200, the moving part 300 and the plug-pull mechanism 400. The support frame 200 is connected to the bottom end of the robot body 100, and the support frame 200 is provided with the accommodating groove 210 recessed towards the ground. The moving part 300 is connected to the support frame 200, and the moving part 300 is arranged on both sides of the accommodating groove 210 along the first direction X. The projection of the moving part 300 along the first direction X at least partially overlaps the projection of the accommodating groove 210 along the first direction X, so that the distance between the bottom surface of the accommodating groove 210 and the ground is small. The plug-pull mechanism 400 is connected to the robot body 100 and can move along the second direction Y to the position where the plug-pull mechanism 400 is located in the accommodating groove 210, so that the distance between the plug-pull mechanism 400 and the ground G is also small. Thus, the plug-pull mechanism 400 can conveniently plug and pull the computing device 30 located in the slot 21 of the lowermost layer of the cabinet 20.

[0076] Please continue to refer to Figure 6 and Figure 7 As shown in the figures, the support frame 200 includes the support frame body 220 and the mounting arm 230. The support frame body 220 includes the bottom wall 221 and the side wall 222 arranged on both sides of the bottom wall 211 along the first direction X. The bottom wall 221 and the side wall 222 surround to form the accommodating groove 210. The mounting arm 230 is connected to one end of the side wall 222 away from the bottom wall 221, and the mounting arm 230 extends away from the accommodating groove 210. The moving part 300 is connected to the mounting arm 230.

[0077] The outer contour of the plug-pull mechanism 400 is a cuboid structure. Therefore, the two side walls 222 are connected to both sides of the bottom wall 221 along the first direction X to form the U-shaped accommodating groove 210. The plug-pull mechanism 400 can move into the accommodating groove 210 from the open side of the accommodating groove 210.

[0078] The mounting arm 230 has a hollow structure, and the moving part can be inserted into the hollow structure. The mounting arm 230, the side wall 222 and the ground G can form a mounting space 240. When the moving part 300 is connected to the mounting arm 230, the moving part 300 can be located in the mounting space 240 formed by the mounting arm 230, the side wall 222 and the ground G. The moving part 300 and the side wall 222 at least partially overlap in the second direction Y. Thus, when the height of the bottom wall 221 from the ground G is reduced, the mounting space 240 for accommodating the moving part 300 can also be formed by connecting the mounting arm 230, so as to reduce the size of the operation and maintenance robot 10 in the first direction X.

[0079] Figure 8 Another structure diagram of the support frame and the moving part in the operation and maintenance robot provided by the embodiment of the present application.

[0080] Referring to Figure 8 As shown, the bottom wall 221 has a first surface 2211 and a second surface 2212 opposite in the second direction Y, and the first surface 2211 faces the ground G. The mounting arm 230 has a third surface 231 and a fourth surface 232 opposite in the second direction Y, and the third surface 231 faces the ground G. The distance between the second surface 2212 and the fourth surface 232 in the second direction Y is greater than or equal to 1 / 2 of the distance between the third surface 231 and the ground G in the second direction Y, and the distance between the first surface 2211 and the third surface 231 in the second direction Y is less than the distance between the third surface 231 and the ground G in the second direction Y.

[0081] The surface of the bottom wall 221 facing the ground G is the first surface 2211, and the surface of the bottom wall 221 facing away from the ground G is the second surface 2212, which is the bottom surface of the accommodating groove 210. The mounting arm 230 can be a laminated plate-shaped member. The surface of the mounting arm 230 facing the ground G is the third surface 231, and the surface of the mounting arm 230 facing away from the ground G is the fourth surface 232. One end of the moving part 300 abuts against the ground G, and the other end can be connected to the mounting arm 230.

[0082] The distance between the second surface 2212 and the fourth surface 232 in the second direction Y is a first distance D1, which is the size of the accommodating groove 210 in the second direction Y. The distance between the third surface 231 and the ground G is a second distance D2. The first distance D1 and the second distance D2 can be represented by the following relationship: D1≥1 / 2*D2. Thus, the first distance D1 is set to be larger, and the size of the moving part 300 overlapping the accommodating groove 210 in the second direction Y is also larger, which can further reduce the size of the operation and maintenance robot 10 in the second direction Y.

[0083] The distance between the first surface 2211 and the third surface 231 along the second direction Y is a third distance D3, and the relationship between the third distance D3 and the second distance D2 can be represented by D2>D3. Thus, the difference between D2 and D3 is the first gap F1 between the first surface 2211 and the ground G. By setting the first gap F1, the first surface 2211 can be suspended relative to the ground G to avoid friction caused by the first surface 2211 contacting the ground G when the maintenance robot 10 moves.

[0084] In a possible implementation, the distance between the first surface 2211 and the ground G is less than or equal to about 20 mm.

[0085] The distance between the first surface 2211 and the ground G is a fourth distance D4. If the fourth distance D4 is too large, the distance between the accommodation groove 210 and the ground G is too large, making it difficult for the plug-in mechanism 400 to move to align with the groove position 21 of the lowermost layer of the cabinet 20. The fourth distance D4 can be less than or equal to 20 mm, so that the distance between the accommodation groove 210 and the ground G is as close as possible without the first surface 2211 contacting the ground G. It should be noted that the fourth distance D4 less than or equal to about 20 mm means that the fourth distance D4 can be less than or equal to a value slightly larger than 20 mm, such as 21 mm or 22 mm, and the fourth distance D4 can also be less than or equal to a value slightly smaller than 20 mm, such as 19 mm or 18 mm.

[0086] In a possible implementation, the distance between the first surface 2211 and the second surface 2212 is greater than or equal to about 30 mm and less than or equal to about 50 mm.

[0087] The distance between the first surface 2211 and the second surface 2212 is the thickness H1 of the bottom wall 221. The thickness H1 of the bottom wall 221 needs to meet the support strength requirement of the maintenance robot 10, and thus the thickness H1 of the bottom wall 221 can be greater than or equal to 30 mm. The smaller the thickness H1 of the bottom wall 221, the closer the distance between the bottom surface of the accommodation groove 210 and the ground G. Thus, the thickness H1 of the bottom wall 221 can be less than or equal to 50 mm while ensuring the support strength of the maintenance robot 10.

[0088] It should be noted that the thickness H1 less than or equal to about 50 mm means that the thickness H1 can be less than or equal to a value slightly larger than 50 mm, such as 51 mm or 52 mm, and the thickness H1 can also be less than or equal to a value slightly smaller than 50 mm, such as 49 mm or 48 mm. The thickness H1 greater than or equal to about 30 mm means that the thickness H1 can be greater than or equal to a value slightly larger than 30 mm, such as 31 mm or 32 mm, and the thickness H1 can also be greater than or equal to a value slightly smaller than 30 mm, such as 29 mm or 28 mm.

[0089] The distance between the second surface 2212 and the ground G is the sum of the thickness H1 of the bottom wall 221 and the fourth distance D4, that is, the distance between the second surface 2212 and the ground G is less than or equal to 70 mm, so the plug-in mechanism 400 can be moved to a position 70 mm away from the ground G. The distance between the slot 21 on the lowermost layer of the cabinet 20 and the ground G is usually greater than 100 mm, so the plug-in mechanism 400 can be aligned with the slot 21 on the lowermost layer of the cabinet 20 to meet the plug-in requirements of the computing device 30 in the slot 21 on the lowermost layer of the cabinet.

[0090] Figure 9 Another structural schematic view of the support frame and the moving part in the operation and maintenance robot provided by the embodiment of the present application.

[0091] Referring to Figure 9 As shown, the support frame 200 further comprises a first reinforcing plate 250, the first reinforcing plate 250 has two adjacent side edges, one of which is connected with the side wall 222, and the other is connected with the mounting arm 230.

[0092] The connection between the mounting arm 230 and the side wall 222 has relatively low strength, which can be increased by the first reinforcing plate 250. The first reinforcing plate 250 can be a reinforcing angle plate, the first reinforcing plate 250 has two adjacent side edges, one of which is connected with the side wall 222, and the other is connected with the mounting arm 230, thereby increasing the strength of the connection between the mounting arm 230 and the side wall 222, so that the overall strength of the support frame 200 is relatively high.

[0093] Please continue to refer to Figure 6 and Figure 9 As shown, the support frame 200 further comprises a second reinforcing plate 260, and the support frame body 220 further comprises an extension wall 223 extending from both sides of the bottom wall 221 along the first direction X, the second reinforcing plate 260 has two opposite side edges, one of which is connected with the mounting arm 230, and the other is connected with the extension wall 223.

[0094] The second reinforcing plate 260 can be rectangular, and has opposite third and fourth side edges 261 and 262. The two extension walls 223 are located on opposite sides of the bottom wall 221 along the first direction X, and extend to be aligned with the mounting arm 230 along the second direction Y. The third side edge 261 of the second reinforcing plate 260 is connected to the mounting arm 230, and the fourth side edge 262 of the second reinforcing plate 260 is connected to the extension wall 223, so that the side of the mounting arm 230 away from the side wall 222 is not suspended, thereby increasing the overall strength of the support frame 200. The first reinforcing plate 250 and the second reinforcing plate 260 are arranged by using the space of the mounting space 240 along the second direction, so that the strength of the support frame 200 is increased without increasing the height of the bottom surface of the containing groove 210 from the ground G, so that the support frame 200 can have high strength and low height.

[0095] Please continue to refer to Figure 6 and Figure 9 As shown in FIGS. 11 and 12, the mounting arm 230 extends along the third direction Z, and the moving part 300 is a wheel assembly. The mounting arm 230 is provided with a wheel assembly at both ends thereof along the third direction Z.

[0096] The side wall 222 is connected with the mounting arm 230 on both sides thereof along the first direction X. Each mounting arm 230 is connected with a wheel assembly at both ends thereof along the third direction Z. Thus, the support frame 200 is connected with four wheel assemblies, which are arranged at the four top corners of the support frame 200. Thus, the wheel assemblies can drive the operation and maintenance robot 10 to move stably.

[0097] Figure 10 The setting mode of the moving part and the support frame in the operation and maintenance robot provided by the embodiment of the present application is shown in FIGS. 13 and 14. Figure 1 ; Figure 11 The structure of the driving wheel assembly in the operation and maintenance robot provided by the embodiment of the present application is shown in FIGS. 15 and 16.

[0098] Referring to Figure 10 and Figure 11 As shown in FIGS. 15 and 16, the wheel assembly is a driving wheel assembly 310, which includes a first chassis 311, a first universal wheel 312, and a driving assembly 313. The first universal wheel 312 and the driving assembly 313 are connected to the first chassis 311. The first chassis 311 is connected to the mounting arm 230. The driving assembly 313 is used to drive the first universal wheel 312 to move or turn.

[0099] All four wheel assemblies can be drive wheel assemblies 310. Each drive wheel assembly 310 includes a first chassis 311, which supports a first omnidirectional wheel 312 and a drive assembly 313. The first omnidirectional wheel 312 and the drive assembly 313 can be connected to opposite sides of the first chassis 311 along a third direction Z. In one possible implementation, the first chassis 311 has a first mounting hole 3111, and the third surface 231 of the mounting arm 230 has a second mounting hole (not shown in the figure). Fasteners can be inserted into the first mounting hole 3111 and the second mounting hole to connect the first chassis 311 to the mounting arm 230. The first chassis 311 can also be connected to the mounting arm 230 by snap-fit ​​or other means. The first omnidirectional wheel 312 faces the ground G, thereby allowing the drive wheel assembly 310 to be connected to the support frame 200 via the first chassis 311.

[0100] The drive assembly 313 may include a first drive element 3131 and a second drive element 3132. Both the first drive element 3131 and the second drive element 3132 may be drive motors. The first drive element 3131 can drive the first omnidirectional wheel 312 to move, and the second drive element 3132 can drive the first omnidirectional wheel 312 to steer. By configuring all four wheel assemblies as active wheel assemblies 310, the driving force of the wheel assemblies to move the maintenance robot 10 is relatively large.

[0101] Figure 12 This is a schematic diagram illustrating the arrangement of the moving part and support frame in the maintenance robot provided in the embodiments of this application. Figure 2 ; Figure 13 This is a schematic diagram of the driven wheel assembly in the maintenance robot provided in this application embodiment.

[0102] See Figure 12 and Figure 13 As shown, the wheel assembly includes a drive wheel assembly 310 and a driven wheel assembly 320. The drive wheel assembly 310 is arranged opposite each other along one diagonal of the support frame 200, and the driven wheel assembly 320 is arranged opposite each other along the other diagonal of the support frame 200. The driven wheel assembly 320 includes a second chassis 321 and a second omnidirectional wheel 322. The second omnidirectional wheel 322 is connected to the second chassis 321, and the second chassis 321 is connected to the mounting arm 230.

[0103] Two of the wheel assemblies are driving wheel assemblies 310, which are located at opposite ends of one diagonal of the support frame 200. The other two wheel assemblies are driven wheel assemblies 320, which are located at opposite ends of the other diagonal of the support frame 200.

[0104] The specific structure of the drive wheel assembly 310 has been described in detail in the above embodiments, and will not be repeated here.

[0105] In a possible implementation, the second base plate 321 has a third mounting hole 3211, and the third surface 231 of the mounting arm 230 has a fourth mounting hole (not shown in the figure), and a fastener can be inserted into the third mounting hole 3211 and the fourth mounting hole to connect the second base plate 321 and the mounting arm 230. The second base plate 321 can also be connected to the mounting arm 230 by clamping or the like. The second universal wheel 322 faces the ground G, and thus the driven wheel assembly 320 can be connected to the support frame 200 through the second base plate 321. The driven wheel assembly 320 is not provided with a driving device, and moves with the movement of the operation and maintenance robot 10 and supports the robot body 100.

[0106] The active wheel assembly 310 is arranged opposite along one diagonal of the support frame 200, and the driven wheel assembly 320 is arranged opposite along another diagonal of the support frame 200, which can make the driving force more evenly distributed when the operation and maintenance robot 10 moves, and can reduce the cost of the operation and maintenance robot 10.
