Description

Technical Field

[0001] This utility model relates to the field of data center inspection robot technology, and in particular to an omnidirectional wheeled chassis data center inspection robot. Background Technology

[0002] Data center inspection robots, as intelligent devices that replace manual inspections, identify anomalies through edge computing or cloud analysis and promptly push out early warning information, significantly reducing the labor intensity of manual inspections and shortening fault detection time from hours to minutes, thus significantly improving the security and reliability of data centers. Data center server rooms are typically characterized by dense equipment and narrow aisles. Robots need to frequently adjust their inspection direction within these narrow aisles to cover equipment inspection points on the front and sides of server racks, or to move from one aisle to another, achieving comprehensive, blind-spot-free inspection.

[0003] However, existing data center inspection robots have significant deficiencies in their directional adjustment capabilities, making them unsuitable for the inspection needs of confined server room spaces. Most existing inspection robots use wheeled chassis, and their orientation relies on traditional "turning and moving" modes. The orientation of these chassis requires a certain radius. In the narrow aisles of server racks, an excessively large orientation radius prevents the robot from turning in place. During orientation, if the robot cannot accurately control its turning trajectory due to space constraints, it is prone to collisions with rack corners, floor pipes, or other equipment. This can damage the robot's inspection components, loosen rack connections, or damage equipment casings, creating new maintenance risks. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes an omnidirectional wheeled chassis data center inspection robot.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an omnidirectional wheeled chassis data center inspection robot, including a frame, a walking component, and a support component. The walking component is provided on both sides of the outer wall of the frame, and auxiliary wheels are rotatably connected to both the front and rear ends of the frame. The walking component includes a triangular frame and walking wheels. Two triangular frames are symmetrically arranged, and three walking wheels are rotatably connected between the two triangular frames. A toothed ring is horizontally fixed at the center of one end face of each of the two triangular frames, and the other end of the toothed ring is rotatably connected to the outer wall of the frame. The support component includes a rotating frame, which is horizontally fixed on the bottom end face of the frame. A cylindrical frame is vertically rotatably connected to the center of the bottom face of the rotating frame. A support plate is vertically slidably inserted on the cylindrical frame, and a hydraulic cylinder is vertically fixed on the bottom face of the cylindrical frame, with the bottom end of the hydraulic cylinder fixed to the top face of the support plate.

[0006] As a preferred embodiment, a drive sprocket is horizontally rotatably connected to the middle of the two tripods, and a driven sprocket is fixed on the axle of the traveling wheel.

[0007] As a preferred option, a chain is tensioned and connected to the driving sprocket, and the chain is tensioned and engaged with the driven sprocket.

[0008] As a preferred embodiment, a travel motor is horizontally fixed on the side end face of the frame, and the output end of the travel motor is fixedly assembled with the end of the drive sprocket through a toothed ring.

[0009] As a preferred embodiment, a crawling motor is horizontally fixed on the side end face of the frame, and a crawling gear is fixed to the output end of the crawling motor.

[0010] As a preferred option, the crawling gear meshes with the ring gear.

[0011] As a preferred embodiment, a steering motor is vertically fixed on the top surface of the rotating frame, and a steering gear is horizontally fixed at the output end of the steering motor. A driven gear is horizontally fixed at the top of the cylindrical frame, and the driven gear meshes with the steering gear.

[0012] Compared with existing technologies, the advantages of this invention are as follows: Through the coordinated design of hydraulic lifting and gear steering, the turning radius limitation is completely eliminated. The hydraulic cylinder of the support extends, pushing the support plate vertically downwards and contacting the ground. After continuous extension, the frame and the two side walking components are lifted as a whole, allowing the walking wheels to completely detach from the ground. During this process, the walking wheels do not rub against the ground, avoiding the frictional resistance between the wheels and the ground that limits steering in traditional steering, thus laying the foundation for radius-free steering. The steering motor drives the steering gear to rotate, meshing with the driven gear on the cylinder frame, causing the cylinder frame to deflect as a whole, thereby driving the frame and inspection equipment to turn synchronously. Because the walking wheels are off the ground, the turning process does not rely on ground space, enabling 360° turning in place. After turning, the hydraulic cylinder retracts, causing the support plate to rise, and the walking wheels re-contact the ground. The entire turning process is time-efficient, eliminating the need to retreat to the end of the passage or find an open area like traditional robots, perfectly adapting to the turning needs of narrow passages. This technology allows for direct in-place turning within the passage, saving path length per turn, reducing the inspection cycle for the entire area, and improving inspection efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. 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.

[0016] like Figures 1 to 5As shown, an omnidirectional wheeled chassis data center inspection robot includes a frame 1, walking components 2, and a support component 3. Walking components 2 are installed on both sides of the outer wall of the frame 1, and auxiliary wheels 14 are rotatably connected to both the front and rear ends of the frame 1. Each walking component 2 includes a tripod 21 and two walking wheels 22. Two tripods 21 are symmetrically arranged, and three walking wheels 22 are rotatably connected between the two tripods 21. A toothed ring 23 is horizontally fixed at the center of one end face of each of the two tripods 21, and the other end of the toothed ring 23 is rotatably connected to the outer wall of the frame 1. The support component 3 includes a rotating frame 31, which is horizontally... A cylindrical frame 32 is vertically rotatably connected to the bottom center of the rotating frame 31, fixed to the bottom end of the frame 1. A support plate 33 is vertically slidably inserted on the cylindrical frame 32, and a hydraulic cylinder 34 is vertically fixed to the bottom surface of the cylindrical frame 32. The bottom end of the hydraulic cylinder 34 is fixed to the top surface of the support plate 33. A steering motor 36 is vertically fixed to the top surface of the rotating frame 31, and a steering gear 37 is horizontally fixed to the output end of the steering motor 36. A driven gear 35 is horizontally fixed to the top of the cylindrical frame 32, and the driven gear 35 meshes with the steering gear 37. This is the design of an omnidirectional wheeled chassis data center inspection robot. The frame 1 supports the entire robot structure. The walking component 2 consists of a tripod 21 and walking wheels 22, providing four-way freedom of movement, enabling the robot to flexibly perform inspections in the data center. The auxiliary wheels 14 increase the robot's balance and stability and provide additional steering capability. The rotating frame 31, cylinder frame 32, and support plate 33 in support component 3 constitute the robot's lifting system, driven by hydraulic cylinder 34. The height of the support plate 33 can be adjusted to accommodate inspection equipment at different heights. The steering motor 36, through the meshing of steering gear 37 and driven gear 35, rotates the cylinder frame 32, thereby driving the support plate to rotate 360 ​​degrees. This allows the robot to flexibly adjust the direction of the inspection equipment, achieving omnidirectional, blind-spot-free inspection. In summary, this robot, through multi-directional movement, balanced stability, lifting adjustment, and omnidirectional rotation, effectively improves the flexibility and efficiency of data center inspections.

[0017] In one embodiment, such as Figure 2 and 5 As shown, a drive sprocket 24 is horizontally rotatably connected to the middle of the two tripods 21, and a driven sprocket 25 is fixed on the axle of the traveling wheel 22. A chain 26 is tensioned and connected to the drive sprocket 24, and the chain 26 is in tension engagement with the driven sprocket 25. The function of the drive sprocket 24 is to drive the chain 26 to move through the rotation of the drive sprocket, thereby transmitting power. The driven sprocket 25 fixed on the axle of the traveling wheel 22 transmits and receives power through meshing with the chain 26. The chain 26 serves as the power transmission carrier between the drive sprocket 24 and the driven sprocket 25, ensuring that power can be effectively transmitted from the drive sprocket to the driven sprocket.

[0018] In one embodiment, such as Figure 2 and5 As shown, a travel motor 12 is horizontally fixed on the side end face of the frame 1, and the output end of the travel motor 12 is fixedly assembled with the end of the drive sprocket 24 through the toothed ring 23. The frame 1 is the basic support of the entire device, and the travel motor 12 fixedly installed on its side end face provides the power source responsible for driving the movement of the device. The toothed ring 23, as a transmission component, transmits motion through meshing with the drive sprocket 24. The drive sprocket 24, through its connection with the output end of the travel motor 12, converts the rotational motion of the motor into linear motion, thereby driving the device to move along a predetermined path.

[0019] In one embodiment, such as Figure 2 and 3 As shown, a crawler motor 11 is horizontally fixed to the side end face of the frame 1, and a crawler gear 13 is fixed to the output end of the crawler motor 11. The crawler gear 13 meshes with a gear ring 23. The frame 1, as a supporting part, provides a stable mounting platform. The crawler motor 11 is mounted on the side of the frame 1 and achieves horizontal movement through the crawler gear 13 fixed to its output end. The gear ring 23 serves as the transmission object of the crawler gear 13, and through the meshing between the two, the frame 1 can be precisely controlled to move along a predetermined path.

[0020] The working principle of this utility model: First, a data center inspection device is installed on the top surface of rack 1. During inspection, the walking motor 12 on the side end face of rack 1 is started to drive the drive sprocket 24 of the tripod 21 in the walking component 2 to rotate, which drives the chain 26 to move and tension. The moving chain 26 drives the walking wheel 22 in the tripod 21 to move, which drives rack 1 to move in the computer room and switch the inspection position. Then, when switching the inspection direction, the hydraulic cylinder 34 on the bottom surface of the cylinder frame 32 in the support component 3 extends, pushing the support plate 33 to slide vertically down on the cylinder frame 32, thereby lifting the traveling parts 2 on both sides of the frame 1 off the ground. Then, the steering motor 36 on the top surface of the rotating frame 31 is started. The steering motor 36 drives the steering gear 37 to rotate, meshing with the driven gear 35 on the cylinder frame 32 to deflect on the cylinder frame 32 to switch the direction of travel. Then, the hydraulic cylinder 34 on the bottom surface of the cylinder frame 32 retracts, pushing the support plate 33 to rise vertically on the cylinder frame 32, thereby lifting the traveling parts 2 on both sides of the frame 1 to contact the ground. Finally, when it is necessary to climb the steps, start the crawling motor 11 to drive the crawling gear 13 to rotate, which meshes with the toothed ring 23 at the end of the walking component 2, causing the walking component 2 to rotate on the frame 1, and the three walking wheels 22 to climb the steps.

[0021] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
