Description

Technical Field

[0001] This utility model relates to the field of steering wheel connectors, specifically a steering wheel connector for AGV vehicles. Background Technology

[0002] The AGV steering wheel connector is a functional connection device specifically designed for the core component of AGVs (Automated Guided Vehicles)—the steering wheel—and the AGV frame. It is not a simple "connector" but a modular component that integrates multiple functions such as mechanical connection, power transmission, and deviation adaptation. It typically consists of a metal shell, a drive shaft, a positioning structure, a locking component, and auxiliary maintenance components. It needs to be compatible with the driving torque, steering angle, and installation dimensions of the AGV steering wheel and the frame. It is a key intermediate carrier to ensure the coordinated operation of the steering wheel and the frame.

[0003] However, conventional connectors currently have a cumbersome installation process and a very low fault tolerance rate. They generally use rigid bolt fastening schemes, which have strict requirements for the coaxiality of the steering wheel output shaft and the vehicle frame power input shaft. Once the deviation exceeds the standard, it will directly lead to transmission jamming, bearing stress concentration, and even spindle deformation. In actual assembly, operators need to rely on laser alignment instruments for repeated calibration. At the same time, it is very easy to cause loosening at the connection between the connector and the steering wheel and the vehicle frame, requiring frequent shutdowns for debugging. To address this, we propose a steering wheel connector for AGV vehicles. Utility Model Content

[0007] As a further embodiment of this utility model: the bottom end of the driven shaft is connected to a base, the bottom surface of the base is connected to a drive frame, and the output end of the drive frame is connected to a drive wheel.

[0008] As a further improvement of this utility model: an upper locking frame is provided above the connecting plate, and a set of limiting slide rods are connected to the bottom surface of the upper locking frame.

[0009] As a further embodiment of this utility model: the bottom surface of each of the limiting slide rods is connected to a lower locking frame, the bottom surface of the upper locking frame is connected to a first positive and negative threaded sleeve, the upper surface of the lower locking frame is connected to a second positive and negative threaded sleeve, the inner wall of the first positive and negative threaded sleeve and the inner wall of the second positive and negative threaded sleeve are threadedly connected to a positive and negative screw, and the top end of the positive and negative screw penetrates the upper locking frame and extends to the top of the upper locking frame.

A driven shaft 4 is snapped onto the bottom surface of the connecting plate 1. The top end of the driven shaft 4 passes through the connecting plate 1 and extends above it. The output end of the steering drive motor 3 passes through the connecting plate 1 and extends above it. A drive gear 8 is connected to the output end of the steering drive motor 3. A driven gear 9 is connected to the top end of the driven shaft 4. The moving gear 9 meshes with the drive gear 8, and the steering drive motor 3 drives the drive gear 8 to rotate. By meshing with the driven gear 9, the driven shaft 4 is driven, which in turn causes the drive wheel 7 to turn. The lubricating oil tank 10 supplies oil to the drive gear 8 for lubrication through the output valve 11. The upper locking frame 12 and the lower locking frame 18 are guided by the limiting slide rod 13. Rotating the rotating nut 19 drives the positive and negative screws 16, so that the first positive and negative screw sleeves 14 and the second positive and negative screw sleeves 15 drive the locking block 20 to be embedded in the mounting groove 21 of the connecting frame 2, thereby achieving locking with the frame, greatly shortening the installation time and reducing the operating threshold.

[0022] In this embodiment, a lubricating oil tank 10 is connected to the bottom surface of the connecting plate 1, and an output valve 11 is connected to the bottom surface of the connecting plate 1. The input end of the output valve 11 is connected to the lubricating oil tank 10 through a conduit, and the output end of the output valve 11 passes through the connecting plate 1 through a conduit and extends to the top of the connecting plate 1. The output end of the output valve 11 contacts the drive gear 8, which can lubricate the gear plate. A base 5 is connected to the bottom end of the driven shaft 4, and a drive frame 6 is connected to the bottom surface of the base 5. A drive wheel 7 is connected to the output end of the drive frame 6, and the drive frame 6 can drive the drive wheel 7 to move. An upper locking frame 12 is provided above the connecting plate 1, and a set of limiting slide rods 13 is connected to the bottom surface of the upper locking frame 12. The movement stability of the upper locking frame 12 can be improved by setting the limiting slide rods 13.

[0023] In this embodiment, the bottom surface of each limiting slide bar 13 is connected to a lower locking frame 18, the bottom surface of the upper locking frame 12 is connected to a first positive and negative threaded sleeve 14, the upper surface of the lower locking frame 18 is connected to a second positive and negative threaded sleeve 15, the inner wall of the first positive and negative threaded sleeve 14 and the inner wall of the second positive and negative threaded sleeve 15 are threadedly connected to a positive and negative screw 16, the top end of the positive and negative screw 16 passes through the upper locking frame 12 and extends to the top of the upper locking frame 12, and by rotating the positive and negative screw 16, a rotating nut 19 can be connected to the top end of the positive and negative screw 16. A set of mounting positioning blocks 17 is connected to the upper surface of the upper locking frame 12, the first positive and negative threaded sleeve 14 and the second positive and negative threaded sleeve 15 are close to each other, and two locking blocks 20 are connected to the side of the lower locking frame 18 and the upper locking frame 12 that are close to each other. Both sets of locking blocks 20 are engaged with the connecting frame 2 through the mounting groove 21. The connecting plate 1 can be locked by the locking blocks 20.

[0024] Working principle: The connecting plate 1 serves as a support, connecting two connecting frames 2 on the top and a steering drive motor 3 and driven shaft 4 on the bottom. The bottom end of the driven shaft 4 is connected to the drive frame 6 and drive wheel 7 via the base 5. During operation, the steering drive motor 3 drives the drive gear 8 to rotate, which drives the driven shaft 4 by meshing with the driven gear plate 9, thereby causing the drive wheel 7 to turn. The lubricating oil tank 10 supplies oil to the drive gear 8 for lubrication through the output valve 11. The upper locking frame 12 and the lower locking frame 18 are guided by the limit slide rod 13. Rotating the rotating nut 19 drives the positive and negative screws 16, so that the first positive and negative screw sleeve 14 and the second positive and negative screw sleeve 15 drive the locking block 20 to be embedded into the mounting groove 21 of the connecting frame 2, thereby locking it with the vehicle frame. During operation, first align the mounting positioning block 17 for positioning, then rotate the rotating nut 19 clockwise to tighten it, adjust the steering drive motor 3 and drive frame 6 to ensure smooth operation, and open the output valve 11 to lubricate the gear.
