Description

Technical Field

[0001] This utility model relates to the field of AGV vehicle mechanical structure technology, and more specifically, to an AGV vehicle steering encoder mounting device. Background Technology

[0002] Steering encoders play a crucial role in AGV systems, providing feedback on the speed and position of the steering motors to achieve closed-loop control. Using the data provided by the encoders, the AGV system can monitor the motor's operating status in real time, enabling precise positioning and motion control.

[0003] There are generally two layout options for existing steering encoders: one is an internal encoder, typically referring to the steering encoder integrated into the servo steering motor, measuring position and speed through the rotation of the motor shaft. The other is an external encoder, usually installed as a separate device outside the steering motor, mechanically connected to the motor shaft to obtain precise position information, providing external position feedback. For AGVs, the steering encoder generally obtains signals from the steering motor by meshing with gears on the output shaft. However, existing internal encoders are unstable and prone to detachment, leading to AGV downtime and impacting work efficiency.

[0004] Therefore, how to provide an AGV vehicle steering encoder mounting device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0030] like Figure 1 and Figure 2 As shown, this utility model embodiment provides an AGV vehicle steering encoder mounting device, including: mounting component 1, transmission component 2 and drive component 3.

[0031] Mounting assembly 1 includes mounting plate 11, coupling 12 and steering wheel plate 13. Steering encoder 4 is mounted on mounting plate 11, and the output shaft of steering encoder 4 passes through mounting plate 11 and is connected to the first end of coupling 12. The second end of coupling 12 is connected to steering wheel plate 13.

[0032] The transmission assembly 2 includes a first transmission gear 21, a second transmission gear 22 and a transmission part. The two ends of the transmission part are respectively connected to the second end of the coupling 12 and the center position of the first transmission gear 21. The second transmission gear 22 is horizontally arranged with the first transmission gear 21 and meshes with each other.

[0033] The drive assembly 3 is connected to the second transmission gear 22 to drive the second transmission gear 22 to rotate.

[0034] This invention mounts a steering encoder 4 on a mounting plate 11, with the output shaft of the encoder 4 passing through the mounting plate 11 and connected to the first end of a coupling 12. The second end of the coupling 12 is connected to a steering wheel plate 13. Both ends of the transmission unit are connected to the second end of the coupling 12 and the center position of the first transmission gear 21, respectively. The second transmission gear 22 is horizontally positioned and meshes with the first transmission gear 21. The drive assembly 3 is connected to the second transmission gear 22. In use, the drive assembly 3 drives the second transmission gear 22 to rotate, which in turn drives the meshing first transmission gear 21 to rotate, thus rotating the transmission unit. The rotation of the transmission unit drives the coupling 12 to rotate, enabling the steering encoder 4 to provide feedback on the speed and position information of the steering motor 31. This invention fixes the steering encoder 4 and mounting plate 11 to the steering wheel plate 13 of the AGV steering wheel, so that the steering encoder 4 mounting device floats together with the AGV steering wheel, increasing reliability and preventing detachment. In addition, the AGV vehicle steering encoder mounting device of this invention has a compact structure, solves the installation problem of the steering encoder 4, increases structural stability, and improves work efficiency.

[0035] Furthermore, the diameter of the first transmission gear 21 is larger than the diameter of the second transmission gear 22, and the diameter of the first transmission gear 21 is larger than the diameter of the coupling 12. Connecting the smaller diameter coupling 12 with the larger diameter first transmission gear 21 ensures the consistency of rotation between the first transmission gear 21 and the encoder, thereby improving steering accuracy.

[0036] Furthermore, both the first transmission gear 21 and the second transmission gear 22 are made of steel, which avoids incomplete meshing of gears due to long-term wear and improves the service life of the AGV vehicle steering encoder mounting device of this utility model.

[0037] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, such as Figure 1 and Figure 2 As shown, the mounting assembly 1 also includes a plurality of fixed shafts 14, which are spaced apart circumferentially along the coupling 12, and the two ends of the fixed shafts 14 are respectively connected to the mounting plate 11 and the steering wheel plate 13.

[0038] This invention improves the stability of the device by arranging fixed shafts 14 at intervals along the circumference of coupling 12 and connecting both ends of fixed shafts 14 to mounting plate 11 and steering wheel plate 13 respectively.

[0039] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, the mounting plate 11 and the steering wheel plate 13 are respectively provided with a first connecting hole 15 and a second connecting hole 16, and the first connecting hole 15, the second connecting hole 16, the coupling 12, the transmission part and the first transmission gear 21 are coaxially arranged.

[0040] Specifically, the output shaft of the steering encoder 4 passes through the first connecting hole 15 and is connected to the first end of the coupling 12, and the transmission part passes through the second connecting hole 16 and is connected to the second end of the coupling 12.

[0041] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, such as Figure 1 and Figure 2 As shown, the transmission unit includes a bearing 23, a mounting base 24, and a connecting shaft 25. The top of the mounting base 24 is connected to the steering wheel plate 13. The connecting shaft 25 is disposed inside the mounting base 24. The bearing 23 is sleeved on the connecting shaft 25. The first end of the connecting shaft 25 is connected to the second end of the coupling 12. The second end of the connecting shaft 25 is connected to the first transmission gear 21.

[0042] This utility model sets the connecting shaft 25 inside the mounting base 24, sleeves the bearing 23 on the connecting shaft 25, connects the first end of the connecting shaft 25 to the second end of the coupling 12, and connects the second end of the connecting shaft 25 to the first transmission gear 21. Thus, during the rotation of the first transmission gear 21, the connecting shaft 25 can be stably driven to rotate.

[0043] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, such as Figure 1 and Figure 2 As shown, the transmission part also includes a fastening bolt 26 and a mounting hole. The mounting hole is located at the second end of the connecting shaft 25, and the fastening bolt 26 passes through the first transmission gear 21 and is threadedly connected to the mounting hole.

[0044] This invention prevents the first transmission gear 21 from slipping and disengaging, thus avoiding inaccurate and unstable measurements by setting the mounting hole at the second end of the connecting shaft 25 and threading the fastening bolt 26 through the first transmission gear 21 and connecting it to the mounting hole.

[0045] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, such as Figure 1 and Figure 2 As shown, the transmission part also includes a limiting plate 27 and a limiting hole 28. The limiting plate 27 is connected to both ends of the mounting base 24, and the limiting hole 28 is provided on the limiting plate 27.

[0047] Specifically, fixing screws are installed on the fixing shaft 14 to make the fixing shaft 14 stably fixed on the steering wheel plate 13.

[0048] This utility model connects the two ends of the limiting plate 27 and the mounting base 24, sets the limiting hole 28 on the limiting plate 27, and makes two fixing holes 17 correspond to the limiting hole 28. The fixing shaft 14 passes through the fixing hole 17 and the limiting hole 28, thereby fixing the mounting base 24 on the steering wheel plate 13.

The steering motor 31 is mounted on the fixed base 32, and the output shaft of the steering motor 31 is connected to the second transmission gear 22.

[0050] This invention mounts the steering motor 31 on the fixed base 32 and connects the output shaft of the steering motor 31 to the second transmission gear 22. When the steering motor 31 is working normally, it drives the second transmission gear 22 to rotate, which in turn drives the first transmission gear 21 to rotate, so that the steering encoder 4 can feed back the speed and position information of the steering motor 31.

[0051] In one embodiment of the AGV vehicle steering encoder mounting device of this utility model, such as Figure 1 and Figure 2 As shown, the drive assembly 3 also includes a third connecting hole 33 and a fixing bolt, with the third connecting hole 33 located on both sides of the fixing base 32.

[0052] The steering wheel plate 13 is provided with two sides of the clearance opening 18 and a fourth connecting hole 19. The fourth connecting hole 19 is located on both sides of the clearance opening 18. The clearance opening 18 is engaged with the steering motor 31.
