Abstract
Description
Technical Field
[0001] This application relates to a fixed mechanism, chassis, and intelligent guided vehicle, belonging to the field of intelligent transportation equipment. Background Technology
[0002] With the rapid development of intelligent manufacturing, Intelligent Guided Vehicles (IGVs) play a crucial role in automation fields such as modern logistics and port production. Especially in automated container terminals, IGVs, as the core equipment for horizontal transportation, directly determine the efficiency and safety of material handling and production tasks through their precise navigation and control capabilities.
[0003] The angle encoder is a key sensor for IGVs to acquire vehicle steering angle information, and its reliability directly affects the overall performance of the system. However, in complex environments such as automated docks, uneven ground can cause strong vibrations and bumps when vehicles are in motion, potentially damaging, loosening, or causing connectors to detach from the angle encoder's communication cable, thus affecting the stability of signal transmission. If the encoder or communication cable malfunctions, it may lead to the failure of the IGV steering control system, causing safety accidents or production interruptions.
[0004] Currently, encoder communication cables are mostly secured using simple binding, conventional cable trays, or simply left suspended. These methods have the following problems:
[0005] 1. The fixed position, height, or angle of the communication cable cannot be adjusted: it cannot effectively cope with the problems of vibration, pulling, and excessive bending damage caused by the complex movement of the vehicle.
[0006] 2. Lack of buffer and limit: During frequent vehicle turning and acceleration / deceleration, communication lines are prone to loosening, displacement or damage due to excessive pulling and bending, which can lead to signal transmission interruption or instability. Summary of the Invention

[0009] Furthermore, the frame fixing assembly includes: an upper frame fixing plate connected to the communication line fixing plate; a lower frame fixing plate opposite to and fixedly disposed with respect to the upper frame fixing plate; and a space between the upper frame fixing plate and the lower frame fixing plate forming a frame fixing plate.
[0010] Furthermore, the communication line fixing plate, the upper frame fixing plate, and the lower frame fixing plate have the same thickness, and / or the communication line fixing plate, the upper frame fixing plate, and the lower frame fixing plate are all made of stainless steel.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0027] Please refer to Figures 1 to 3 This application provides a fixing mechanism, which includes: a frame fixing assembly 10; a communication line fixing plate 20, which is fixed above the frame fixing assembly 10 by bolt connection, and the frame fixing assembly 10 and the communication line fixing plate 20 form a preset angle. The communication line fixing plate 20 has a plurality of holes for binding cable ties to fix the communication line 31.
[0028] In this embodiment, by loosening the connecting bolts between the communication line fixing plate 20 and the frame fixing assembly 10, the communication line fixing plate 20 can rotate freely around the bolt axis in the horizontal plane, thereby realizing the 360-degree all-round position adjustment of the fixing mechanism in the horizontal plane.
[0029] Please refer to Figure 1 and Figure 3 This demonstrates two installation methods for the fixed mechanism.
[0030] In practical applications, operators can precisely adjust the angle of the communication line fixing plate 20 according to the actual routing requirements of the communication line 31, reducing damage to the communication line 31 caused by unreasonable wiring methods such as bending and twisting, and ensuring stable transmission of communication signals.
[0031] In one embodiment, the surface of the communication line fixing plate 20 is evenly distributed with a plurality of small fixing holes (equivalent to the first hole 21). The distribution of the holes fully considers the common size and shape of the communication line 31, ensuring that the communication line 31 is accurately and securely fixed on the plate, and preventing the communication line 31 from shifting during vehicle operation.
[0032] Specifically, the communication cable 31 is placed between the fixing holes of the communication cable fixing plate 20 so that the communication cable 31 is in full contact with the plate surface. Then, cable ties are used to pass through the multiple fixing holes on the communication cable fixing plate 20 in sequence. After the cable ties are tightened, the communication cable 31 is tightly bound to the plate.
[0033] Alternatively, the cable ties may be made of plastic.
[0034] In one embodiment, the communication line fixing plate 20 has a central bolt fixing hole (equivalent to the second hole 22) on its surface for connection with the frame fixing assembly 10. The hole diameter is adapted to the connecting bolt to ensure the tightness and reliability of the connection.
[0035] In some embodiments, the frame fixing assembly 10 includes: an upper frame fixing plate 14 connected to the communication line fixing plate 20; a lower frame fixing plate 15 opposite to and fixedly disposed with respect to the upper frame fixing plate 14; and a space between the upper frame fixing plate 14 and the lower frame fixing plate 15 forming a fixed frame clamping plate.
[0036] In one embodiment, the communication line fixing plate 20 is located above the upper frame fixing plate 14 and the lower frame fixing plate 15, and bolts are used for fixing by passing through the bolt holes of the communication line fixing plate 20 and the upper frame fixing plate 14.
[0037] In one embodiment, the communication line fixing plate 20 is located on the upper frame fixing plate 14 and the lower frame fixing plate 15, and bolts are used for fixing through the bolt holes of the communication line fixing plate 20, the upper frame fixing plate 14 and the lower frame fixing plate 15.
[0038] In one embodiment, the nut is a lock nut, which employs a conventional lock structure combining a nylon ring and a thread-locking agent coating. During bolt tightening, the nylon ring is compressed and deformed, filling the gap between the bolt and nut threads. Simultaneously, the thread-locking agent coating cures, further enhancing the friction between the threads. This effectively prevents the bolt from loosening due to harsh conditions such as vehicle vibration and driving bumps, avoiding malfunctions such as displacement, shaking, or even detachment of the communication line 31 caused by loose connections, thus ensuring the normal operation of the communication system.
[0039] In one embodiment, the upper frame fixing plate 14 and the lower frame fixing plate 15 are matched in shape and size, and are both manufactured using precision machining processes, with uniform and consistent thickness.
[0040] In some embodiments, the communication line fixing plate 20, the upper frame fixing plate 14, and the lower frame fixing plate 15 have the same thickness, and / or the communication line fixing plate 20, the upper frame fixing plate 14, and the lower frame fixing plate 15 are all made of stainless steel.
[0041] In one embodiment, all three plates are manufactured using precision machining processes, resulting in uniform thicknesses to ensure better uniformity and stability of the overall structure under stress.
[0042] Optionally, the upper frame fixing plate 14, the lower frame fixing plate 15, and the communication line fixing plate 20 are made of high-strength, flexible, and corrosion-resistant stainless steel.
[0043] In some embodiments, the upper frame fixing plate 14 and the lower frame fixing plate 15 include a plurality of one-to-one corresponding bolt holes, and bolts are connected to the corresponding bolt holes to fix the upper frame fixing plate 14 and the lower frame fixing plate 15; the bolt holes include: a first bolt hole 11 located at the end of the frame fixing plate; a second bolt hole 12 set at a preset distance from the first bolt hole 11, and the preset distance is adapted to the width of the frame plate.
[0044] Furthermore, the second bolt hole 12 is an oblong hole.
[0045] Furthermore, the bolt hole also includes a third bolt hole 13, located at the end of the frame fixing plate away from the first bolt hole 11, for connecting the communication line fixing plate 20, the upper frame fixing plate 14 and the lower frame fixing plate 15.
[0046] Each frame mounting plate has three bolt fixing holes. The front and rear holes are exactly the same size, and the middle hole is an oblong hole (also known as a long oval hole), which is elongated and allows the connected components to be adjusted within a certain range.
[0047] Both the upper frame mounting plate 14 and the lower frame mounting plate 15 are connected to the frame clamping plate via bolt pairs. During installation, first align the upper frame mounting plate 14 and the lower frame mounting plate 15 with their respective mounting positions on the frame, and place them in their pre-set upper and lower positions on the frame clamping plate. Then, insert the bolts into the bolt holes and slotted holes of the upper frame mounting plate 14 and the lower frame mounting plate 15, and tighten the nuts. The tension of the bolts causes the upper and lower frame mounting plates 15 to fit tightly against the surface of the frame clamping plate, like a strong clamp, firmly holding the frame in place, forming a highly stable rigid connection structure.
[0048] It is worth noting that this structure can prevent additional harmful vibrations caused by the bracket loosening, providing a solid and reliable support foundation for the communication line 31 and ensuring the stable operation of the communication system in complex vehicle operating environments.
[0049] In some embodiments, the communication line fixing plate 20 includes: a first panel 23 having a plurality of first holes 21 for fixing the communication line 31; a bending portion 24 connected to the first panel 23 to raise the first panel 23 to a preset height; and a second panel 25 connected to the bending portion 24 having at least one second hole 22 for connecting to the frame fixing assembly 10.
[0050] When the preset height cannot meet the setting requirements, a shim for adjusting the height is provided between the second panel 25 and the frame fixing assembly 10.
[0051] Specifically, the height can be freely adjusted by increasing or decreasing the number of bolt pads between the communication line fixing plate 20 and the upper frame fixing plate 14, or by selecting pads of different sizes.
[0052] In one embodiment, the shims are typically made of metal or rubber with a certain degree of hardness and wear resistance, and their thickness varies. When the bracket height needs to be increased, an appropriate number of shims can be added between the communication line fixing plate and the frame fixing plate; conversely, if the bracket height needs to be decreased, the number of shims is reduced. This adjustment method is simple to operate and highly precise, effectively compensating for inconsistencies in the height of the communication line 31 caused by differences in vehicle models, variations in the length of the communication line 31, or other factors. This ensures that the communication line 31 is always at the appropriate tension, preventing damage to the internal cable structure due to excessive bending, thereby guaranteeing the integrity and functionality of the communication line.
[0053] In some embodiments, a chassis is provided, comprising: a frame including a frame plate; a steering encoder 30 disposed at one end of the frame plate to detect wheel steering information, wherein the output direction of its communication line 31 is adjustable; and a fixing mechanism as described in the above embodiments, wherein the communication line fixing plate 20 is used to fix the communication line 31.
[0054] It is understandable that the angle encoder 30 can be directly mounted on the motor shaft or on the drive shaft; there is no limitation here.
[0055] For example, one end of the frame plate has a mounting hole for mounting an angle encoder 30, the lower part of which is connected to the motor shaft end to detect wheel steering information. The other end of the frame plate is connected to a support member.
[0056] Typically, the output direction of the communication line 31 of the angle encoder 30 is adjusted via a rotatable connector.
[0057] In some embodiments, an intelligent guided vehicle is provided, which includes the chassis described in the above embodiments.
[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
