Description

Technical Field

[0001] This invention relates to the field of automated guided vehicles (AGVs), and more specifically, to an AGV for industrial production and distribution. Background Technology

[0002] Automated Guided Vehicles (AGVs) are driverless material handling equipment that can automatically travel along preset paths and programs, playing a vital role in industrial production, warehousing, and logistics. AGVs are typically equipped with advanced navigation systems, such as laser navigation, visual navigation, and magnetic navigation, to ensure precise path selection and positioning. They also possess intelligent control systems that can seamlessly integrate with a company's production management system, enabling automated material handling, storage, and distribution. With their high efficiency, accuracy, flexibility, and safety, AGVs not only reduce labor costs and improve production efficiency but also effectively enhance the intelligence level of logistics management.

[0003] In existing technologies, the lifting mechanisms used in automated guided vehicles (AGVs) for industrial production are mostly driven by hydraulic cylinders. However, the precision and control of hydraulic cylinder-driven lifting are primarily affected by the compressibility of hydraulic oil, oil temperature variations, and the accuracy of control valves, limiting it to centimeter-level accuracy. Its speed adjustment range is narrow, and its response is slow. When applied to high-precision operations such as the precise handling and placement of materials in electronic component assembly lines, its lifting precision and response speed are insufficient to meet the requirements of current work scenarios. Furthermore, hydraulic drive systems are significantly affected by ambient temperature changes; the viscosity of the hydraulic oil changes significantly with temperature. Increased viscosity at low temperatures may lead to difficulties in starting the hydraulic system and sluggish operation, while decreased viscosity at high temperatures may cause increased leakage and unstable system pressure. Therefore, there is an urgent need for an AGV suitable for high-precision operations that meets the requirements for high performance, high reliability, and energy efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automated guided vehicle for industrial production and distribution to solve the aforementioned technical problems.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0006] This invention provides an automated guided vehicle for industrial production and distribution, comprising: a guide vehicle body, a lifting mechanism, a collision avoidance mechanism, and a moving mechanism;

[0007] The lifting mechanism is installed on the guide vehicle body. The lifting mechanism includes a lifting plate, a drive source, a gear transmission assembly, four lifting sleeves, and four transmission screws. The lifting plate is located on the top of the guide vehicle body. The four lifting sleeves are evenly and fixedly installed on the bottom of the lifting plate. The four lifting sleeves are threaded onto the outside of several transmission screws. The bottom ends of the four transmission screws are rotatably connected to the inside of the guide vehicle body. The drive end of the drive source is connected to the gear transmission assembly. The gear transmission assembly is connected to the four transmission screws.

[0008] The gear transmission assembly includes a first bevel gear, a second bevel gear, a drive shaft, a drive belt, two third bevel gears, two fourth bevel gears, two fifth bevel gears, and four pulleys. The first bevel gear is fixed to the drive end of the servo motor. The second bevel gear is rotatably mounted on the inner side of the guide vehicle body, with the bottom of the first bevel gear meshing with one side of the second bevel gear. The drive shaft is rotatably mounted on the inner side of the guide vehicle body. The two third bevel gears are symmetrically fixedly mounted on the outer side of the drive shaft, with the bottoms of the two third bevel gears meshing with the two sides of the second bevel gear respectively. The two fourth bevel gears are symmetrically fixedly mounted at both ends of the drive shaft. The two fifth bevel gears are correspondingly fixedly mounted on the outer side of the two drive screws near the servo motor, and the two fourth bevel gears mesh with the two fifth bevel gears. The four pulleys are correspondingly fixedly mounted on the outer side of the four drive screws, and the four pulleys are connected by the drive belt.

[0009] As a further optimization of the present invention, the lifting plate is a rectangular plate, and the four lifting sleeves are distributed at the four corner positions at the bottom of the lifting plate. The driving source is a servo motor, which is fixedly installed on the inner side of the guide vehicle body.

[0010] As a further optimization of the present invention, each of the four corner positions at the bottom of the lifting plate is provided with a sliding limiting assembly. The sliding limiting assembly includes a supporting slide, a limiting rod, a buffer contact body, and a buffer spring. The top of the supporting slide is fixed to the bottom of the lifting plate, and the bottom of the supporting slide contacts the inner side of the guide vehicle body. The bottom of the limiting rod is fixed to the inner side of the guide vehicle body, and one side of the supporting slide is slidably connected to the outer side of the limiting rod. The buffer contact body is slidably sleeved on the top of the limiting rod, and the buffer spring is sleeved on the upper end of the outer side of the limiting rod. Its two ends are fixed to the bottom of the buffer contact body and the outer side of the limiting rod, respectively. The top of the buffer contact body contacts the upper end of the supporting slide.

[0011] As a further optimization of the present invention, the anti-collision mechanism is disposed on one side of the guide vehicle body. The anti-collision mechanism includes an anti-collision body, a lifting drive assembly, and an upward reset assembly. The anti-collision body is slidably installed on one side of the guide vehicle body. One end of the lifting drive assembly is connected to the gear transmission assembly for transmission, and the other end is fixed to one side of the anti-collision body. When the lifting plate moves up, the lifting drive assembly is synchronously driven by the gear transmission assembly, so that the anti-collision body moves down to contact the ground. The upward reset assembly is connected to one side of the anti-collision body and is used to drive the anti-collision body that has descended to the preset position to automatically move up and reset.

[0012] As a further optimization of the present invention, the lifting drive assembly includes a reciprocating screw, a lifting slide, a mating slide shaft, a support spring, a connecting spring, and a rotary drive component. The bottom end of the reciprocating screw is rotatably connected to the inner side of the guide vehicle body. One end of the lifting slide is slidably sleeved on the outer side of the reciprocating screw, and the other end of the lifting slide is slidably connected to one side of the anti-collision body. The support spring is fixedly installed between the lifting slide and the anti-collision body. The mating slide shaft is slidably disposed inside the lifting slide, with one end slidably engaged with the helical groove on the reciprocating screw. The connecting spring is sleeved on the outer side of the mating slide shaft, and its two ends are fixed to the mating slide shaft and the lifting slide, respectively.

[0013] As a further optimization of the present invention, the rotary drive component includes two transmission gears, one of which is fixedly mounted on the lower end of the second bevel gear shaft, and the other transmission gear is fixedly mounted on the lower end of the reciprocating screw, and the two transmission gears mesh with each other.

[0014] As a further optimization of the present invention, the upward resetting component includes a sensing trigger and several sliding limiters. The sensing trigger is set at a position corresponding to the lifting slide and the mating slide. After the lifting slide descends to a preset position, the sensing trigger senses the position of the lifting slide and drives the mating slide to slide and separate from the spiral groove on the reciprocating screw. Several sliding limiters are evenly distributed on one side of the anti-collision body, which are used to slide and limit the moving anti-collision body and provide elastic potential energy when the anti-collision body descends.

[0015] As a further optimization of the present invention, the sensing trigger includes an electromagnet and an infrared sensor. The electromagnet is installed inside the lifting slide and aligned with the end of the mating slide shaft. The electromagnet is electrically connected to the power supply and control unit inside the guide vehicle body. The infrared sensor is installed on the inner side of the guide vehicle body, located below the lifting slide, and is signal-connected to the control unit inside the guide vehicle body.

[0016] As a further optimization of the present invention, the sliding limiting component includes a sliding rod, a pressure spring, and a connecting slider. The bottom end of the sliding rod is used to guide the inner side of the vehicle body for fixing. One end of the connecting slider is slidably sleeved with the outer side of the sliding rod, and the other end is fixed to one side of the anti-collision body. The pressure spring is sleeved on the outer side of the sliding rod, and its two ends are fixed to the connecting slider and the sliding rod, respectively.

[0017] As a further optimization of the present invention, the moving mechanism includes two driving components, two main rolling wheels and four auxiliary rollers. The two main rolling wheels are symmetrically installed in the middle of both sides of the guide vehicle body. The two driving components are correspondingly connected to the two main rolling wheels. The four auxiliary rollers are evenly installed at the bottom of the guide vehicle body.

[0018] The beneficial effects of this invention are as follows:

[0019] The lifting mechanism of this invention mainly adopts the transmission method of motor and transmission screw to realize the lifting action of the lifting mechanism. Compared with the hydraulic drive method of transmission, in terms of precision and control, it adopts the combination of servo motor and gear transmission component to achieve precise control of the height of the lifting plate. The positioning accuracy can reach the millimeter level, which can be well adapted to high-precision operation scenarios such as the precise handling and placement of materials in electronic component assembly lines.

[0020] In addition, the motor drive system is less affected by changes in ambient temperature and does not have the problem of hydraulic oil leakage. Its performance is relatively stable and reliable, and it can better meet the requirements of modern automated logistics and industrial handling for high performance, high reliability and energy saving and environmental protection.

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0038] Please refer to the following: Figure 1 and Figure 2 An automated guided vehicle (AGV) for industrial production and distribution includes: an AAV body 1, a lifting mechanism 2, an anti-collision mechanism 3, and a moving mechanism 4. The lifting mechanism 2 is mounted on the AAV body 1 and can lift the shelves to be transported. The lifting mechanism 2 includes a lifting plate 21, a drive source 22, a gear transmission assembly 23, four lifting sleeves 24, and four transmission screws 25. The lifting plate 21 is located on top of the AAV body 1 and is rectangular. The four lifting sleeves 24 are evenly fixedly installed at the four corners of the bottom of the lifting plate 21. The four lifting sleeves 24 are threaded onto the outer sides of the four transmission screws 25, and the bottom ends of the four transmission screws 25 are rotatably connected to the inner side of the AAV body 1. The drive source 22 can be a servo motor, which is fixedly installed on the inner side of the AAV body 1. The drive end of the drive source 22 is connected to the gear transmission assembly 23, which in turn is connected to the four transmission screws 25.

[0039] For details, please refer to the following: Figure 3 and Figure 4 The gear transmission assembly 23 includes a first bevel gear 231, a second bevel gear 232, a drive shaft 233, a drive belt 234, two third bevel gears 235, two fourth bevel gears 236, two fifth bevel gears 237, and four pulleys 238. The first bevel gear 231 is fixed to the drive end of the servo motor. The second bevel gear 232 is rotatably mounted on the inner side of the guide vehicle body 1, with the bottom of the first bevel gear 231 meshing with one side of the second bevel gear 232. The drive shaft 233 is rotatably mounted on the inner side of the guide vehicle body 1. The two third bevel gears 235 are symmetrical. The two third bevel gears 235 are fixedly mounted on the outside of the drive shaft 233, and the bottoms of the two third bevel gears 235 mesh with the two sides of the second bevel gear 232 respectively. The two fourth bevel gears 236 are symmetrically fixedly mounted at both ends of the drive shaft 233. The two fifth bevel gears 237 are correspondingly fixedly mounted on the outside of the two drive screws 25 near the servo motor, and the two fourth bevel gears 236 mesh with the two fifth bevel gears 237. The four pulleys 238 are correspondingly fixedly mounted on the outside of the four drive screws 25, and the four pulleys 238 are connected by the drive belt 234.

[0040] It should be noted that when the lifting mechanism 2 is in use, the automated guided vehicle has already moved to the corresponding lifting position at the bottom of the shelf. Then, the servo motor rotates, driving the first bevel gear 231 to rotate. The second bevel gear 232 rotates synchronously with the first bevel gear 231. The two third bevel gears 235 begin to rotate under the drive of the second bevel gear 232, allowing the drive shaft 233 to rotate. The rotation of the drive shaft 233 drives the two fourth bevel gears 236 to rotate together. The two fifth bevel gears 237 are respectively driven by their corresponding fourth bevel gears 236. The movement causes the two drive screws 25 to rotate. Under the combined transmission action of the drive belt 234 and the four pulleys 238, the four drive screws 25 can rotate synchronously, driving the corresponding four lifting sleeves 24 to move upward. Finally, the lifting plate slowly moves upward and lifts the shelf on top. When the shelf moves to the preset height, the servo motor stops rotating, causing the four drive screws 25 to stop rotating at the same time. The threaded engagement between the drive screws 25 and the lifting sleeves 24 automatically locks the position of the lifting plate 21, preventing it from moving downward and thus ensuring the stability of the shelf.

[0041] It should be further explained that the lifting mechanism 2 used in the aforementioned automated guided vehicle has the following advantages compared to the traditional hydraulic lifting method: In terms of precision and control, a servo motor is used as the main drive source 22, which, together with the transmission belt 234, bevel gears, and other components, can achieve precise control of the lifting plate 21 through a precise electronic control system. This enables precise control of the height of the lifting plate 21, with a positioning accuracy of up to the millimeter level. This is well-suited for high-precision operation scenarios such as the precise handling and placement of materials in electronic component assembly lines. In addition, the speed of the servo motor can be flexibly adjusted through devices such as frequency converters, thereby achieving a wide range of adjustment for the lifting speed of the lifting plate 21. The lifting plate 21 can be raised or lowered quickly or slowly according to different operational needs and cargo characteristics. In terms of maintenance and reliability, since the various transmission components of the lifting mechanism 2 are highly standardized mechanical parts, readily available on the market, and with mature maintenance techniques, ordinary maintenance personnel can perform maintenance and replacement after simple training. In contrast, hydraulic cylinders involve a wide variety of hydraulic components such as seals, hydraulic pumps, and control valves, which are diverse in type and specifications, making procurement and replacement relatively difficult. Furthermore, maintenance requires specialized hydraulic knowledge and skills, resulting in higher maintenance costs. Additionally, the motor-driven system eliminates the problem of hydraulic oil leakage, avoiding environmental pollution, equipment contamination, and potential safety hazards such as slippery surfaces causing falls. Hydraulic cylinders, on the other hand, are prone to hydraulic oil leakage due to aging and wear of seals, affecting normal equipment operation and requiring regular seal inspection and replacement, increasing maintenance workload and costs. The servo motor offers higher reliability and is less affected by environmental changes, as its performance is relatively stable and less affected by ambient temperature variations, operating normally over a wide temperature range. The viscosity of hydraulic oil changes significantly with temperature. Increased viscosity at low temperatures can lead to difficulties in starting the hydraulic system and slow operation; decreased viscosity at high temperatures can cause increased leakage and unstable system pressure, affecting the normal operation and reliability of the hydraulic cylinder. Transmission components of motor-driven systems, such as the drive belt 234 and gears, have relatively stable and predictable performance and lifespan under normal maintenance. Hydraulic cylinder systems, however, are prone to valve core jamming and cylinder creep due to impurities and air contamination in the hydraulic oil. These failures are also somewhat random and difficult to predict and prevent, impacting system stability and reliability. In summary, the lifting mechanism 2 of this invention has significant advantages over hydraulic cylinder drives in terms of precision control, ease of maintenance, reliability, spatial layout, and energy efficiency, better meeting the requirements of modern automated logistics and industrial handling for high performance, high reliability, and energy conservation.

[0042] Please refer to the following: Figure 3 , Figure 5 and Figure 6To further improve the stability of the lifting plate 21 during its lifting process and reduce the impact of the load-bearing force on the entire automated guided vehicle, this invention further optimizes the above solution. Specifically, sliding limit components 26 are provided at the four corners of the bottom of the lifting plate 21. Each sliding limit component 26 includes a support slide 261, a limit rod 262, a buffer contact body 263, and a buffer spring 264. The top of the support slide 261 is fixed to the bottom of the lifting plate 21. The bottom contacts the inner side of the guide vehicle body 1. The bottom of the limiting rod 262 is fixed to the inner side of the guide vehicle body 1. One side of the support slide 261 is slidably connected to the outer side of the limiting rod 262. The buffer contact body 263 is slidably sleeved on the top of the limiting rod 262. The buffer spring 264 is sleeved on the upper end of the outer side of the limiting rod 262. Its two ends are fixed to the bottom of the buffer contact body 263 and the outer side of the limiting rod 262, respectively. The top of the buffer contact body 263 contacts the upper end of the support slide 261.

[0043] It should be noted that when the lifting plate 21 moves upward, the support slide 261 moves upward along with the lifting plate 21. One side of the support slide 261 slides along the outer side of the limiting rod 262. Through the cooperation of the four support slides 261 and the four limiting rods 262, the lifting plate 21 is stabilized and limited, allowing it to move smoothly up and down. When the lifting plate 21 moves the shelf downward, after the upper end of the support slide 261 moves downward and contacts the top of the buffer contact body 263, the bottom of the support slide 261 has not yet contacted the inner side of the guide vehicle body 1. As the support slide 261 moves downward, it can drive the buffer contact body 263 downward and simultaneously compress the buffer spring 264. Through the cooperation between the buffer contact body 263 and the buffer spring 264, the downward-moving lifting plate 21 is buffered, which can prevent the support slide 261 from directly and rigidly contacting the guide vehicle body 1, thus providing a certain degree of protection for the guide vehicle body 1.

[0044] Please refer to the following: Figure 7 To further enhance the safety and stability of the automated guided vehicle (AGV) when carrying the rack, and in conjunction with the design of the lifting mechanism 2, this invention further optimizes the above scheme. Specifically, the anti-collision mechanism 3 is located on one side of the vehicle body 1. The anti-collision mechanism 3 includes an anti-collision body 31, a lifting drive assembly 32, and an upward reset assembly 33. The anti-collision body 31 is slidably installed on one side of the vehicle body 1. The bottom periphery of the anti-collision body 31 is provided with a rubber anti-collision layer. One end of the lifting drive assembly 32 is connected to the gear transmission assembly 23, and the other end is fixed to one side of the anti-collision body 31. When the lifting plate 21 moves upward, the lifting drive assembly 32 is synchronously driven by the gear transmission assembly 23, causing the anti-collision body 31 to move downward and contact the ground. The upward reset assembly 33 is connected to one side of the anti-collision body 31 and is used to drive the anti-collision body 31, which has descended to a preset position, to automatically move upward and reset.

[0045] For details, please refer to the following: Figures 8 to 9 The lifting drive assembly 32 includes a reciprocating screw 321, a lifting slide 322, a mating slide shaft 323, a support spring 324, a connecting spring 325, and a rotary drive component. The bottom end of the reciprocating screw 321 is rotatably connected to the inner side of the guide vehicle body 1. The reciprocating screw 321 is provided with threaded grooves with opposite helical directions. One end of the lifting slide 322 is slidably sleeved on the outer side of the reciprocating screw 321, and the other end of the lifting slide 322 is slidably connected to one side of the anti-collision body 31. The support spring 324 is fixedly installed between the lifting slide 322 and the anti-collision body 31. The mating slide shaft 323 is slidably disposed inside the lifting slide 322, and one end of it is slidably engaged with the helical groove on the reciprocating screw 321. The connecting spring 325 is sleeved on the outer side of the mating slide shaft 323, and both ends of it are fixed to the mating slide shaft 323 and the lifting slide 322, respectively. The rotary drive includes two transmission gears 326. One transmission gear 326 is fixedly mounted on the lower end of the shaft of the second bevel gear 232, and the other transmission gear 326 is fixedly mounted on the lower end of the reciprocating screw 321. The two transmission gears 326 mesh with each other.

[0046] Please refer to the following: Figures 8 to 10 The upward reset assembly 33 includes a sensing trigger and two sliding limiters. The sensing trigger is positioned at the corresponding position of the lifting slide 322 and the mating slide. After the lifting slide 322 descends to a preset position, the sensing trigger senses the position of the lifting slide 322 and drives the mating slide to slide and separate from the spiral groove on the reciprocating screw 321. The two sliding limiters are evenly distributed on one side of the anti-collision body 31, which are used to slide and limit the movement of the anti-collision body 31 and provide elastic potential energy when the anti-collision body 31 descends. The sensing trigger includes an electromagnet 331 and an infrared sensor 332. The electromagnet 331 is installed inside the lifting slide 322 and aligned with the end of the mating slide shaft 323. The electromagnet 331 is electrically connected to the power supply and control unit inside the guide vehicle body 1. The infrared sensor 332 is installed inside the guide vehicle body 1, below the lifting slide 322, and is signal-connected to the control unit inside the guide vehicle body 1. The sliding limit component includes a slide rod 333, a pressure spring 334, and a connecting slider 335. The bottom end of the slide rod 333 is used to guide the inner side of the vehicle body 1 for fixing. One end of the connecting slider 335 is slidably sleeved with the outer side of the slide rod 333, and the other end is fixed with one side of the anti-collision body 31. The pressure spring 334 is sleeved on the outer side of the slide rod 333, and its two ends are fixed with the connecting slider 335 and the slide rod 333 respectively.

[0047] It should be noted that, in use, the aforementioned anti-collision mechanism 3 drives the gear transmission assembly 23 to move by the forward rotation of the servo motor, which in turn moves the lifting plate 21 upward. At this time, the rotation of the second bevel gear 232 causes the two transmission gears 326 to rotate synchronously. The reciprocating screw 321 is driven by the transmission gears 326 and begins to rotate. Since the sliding shaft 323 engages with the first helical groove on the reciprocating screw 321, and this helical groove is adapted to the forward rotation direction of the servo motor, that is, when the servo motor rotates forward, the rotation of the helical groove can drive the sliding shaft 323 to slide downward. Furthermore, the lifting slide 322 is restricted by the sliding of the guide vehicle body 1, allowing the reciprocating screw 321 to drive the lifting slide 322 to gradually move downward, thus preventing the collision. The anti-collision body 31 moves downward in sync with the lifting slide 322. When the bottom of the anti-collision body 31 descends and contacts the ground, the lifting plate 21 has not yet contacted the shelf. The contact between the anti-collision body 31 and the ground further increases the support of the bottom of the guide vehicle body 1. As the lifting plate 21 continues to move upward and contacts the shelf, lifting the shelf, it can improve the stability of the guide vehicle body 1 and prevent swaying. During the upward movement of the lifting plate 21, the lifting slide 322 continues to extend and slide downward on the surface of the reciprocating screw 321, and begins to compress the support spring 324. During the downward movement of the anti-collision body 31, the two connecting sliders 335 connected to it begin to slide downward along the corresponding slide rods 333, and exert a compressive force on the pressure spring 334 to cause it to contract. When the lifting plate 21... After the shelf is raised to the preset height, the servo motor stops rotating, the lifting plate 21 stops moving upward, the reciprocating screw 321 stops rotating, and the lifting slide 322 reaches the preset position. The position of the lifting slide 322 is detected by the infrared sensor 332 and a signal is sent to the control unit. After receiving the signal, the control unit starts to control the electromagnet 331 to be energized. The electromagnet 331 generates a magnetic force, which attracts the mating slide shaft 323, causing the mating slide shaft 323 to slide and retract into the lifting slide 322. The connecting spring 325 is synchronously stretched by the mating slide shaft 323. When the end of the mating slide shaft 323 contacts the electromagnet 331, the other end of the mating slide shaft 323 separates from the spiral groove on the reciprocating screw 321. At this time, the lifting slide... The lowering slide 322 is no longer locked by the sliding shaft 323, and under the combined elastic force of the support spring 324 and the pressure spring 334, the surface of the reciprocating screw 321 moves upward and resets. The anti-collision body 31 moves upward and resets along with the lowering slide 322, causing the bottom of the anti-collision body 31 to separate from the ground. Then, the infrared sensor detects the change in position of the lowering slide 322 and sends a signal to the control unit again, enabling the control unit to de-energize the electromagnet 331. The sliding shaft 323 loses the magnetic attraction of the electromagnet 331 and slides again under the elastic force of the connecting spring 325, engaging with the helical groove on the reciprocating screw 321. At this time, the reset anti-collision body 31 will no longer obstruct the normal movement of the automated guided vehicle.Once the shelf is moved to the designated position, the lifting plate 21 needs to be lowered to place the shelf in the designated position. The servo motor is then controlled to rotate in the reverse direction, causing the sliding shaft 323 to slide along the second spiral groove on the reciprocating screw 321. This spiral groove is adapted to the reverse rotation of the servo motor, thus driving the sliding shaft 323 to continue lowering, allowing the lifting slide 322 to move downwards. The anti-collision body 31 follows the lifting slide 322 downwards. When the bottom of the anti-collision body 31 contacts the ground, the bottom of the shelf has not yet contacted the ground. At this point, the anti-collision body 31 acts as an auxiliary support structure, providing auxiliary support for the unloading guide vehicle. This continues until the shelf contacts the ground, and after the lifting plate 21 separates from the shelf, the anti-collision body 31 automatically resets.

[0048] As described above, the anti-collision mechanism 3, through its linkage with the lifting mechanism 2, achieves coordinated movement of the lifting plate 21 and the anti-collision body 31. When the lifting plate 21 moves upward to raise the shelf and when the shelf is unloaded, the anti-collision body 31 moves downward simultaneously to support the ground, serving as an auxiliary support structure. This prevents slight swaying when the guide vehicle is transporting heavy shelves, thereby improving the stability and safety of the guide vehicle during loading and unloading. As for the anti-collision mechanism 3, it mainly plays an anti-collision role during the movement of the guide vehicle, and during the loading and unloading process, it also serves as an auxiliary support structure. Through its linkage with the lifting mechanism 2, it eliminates the need for a separate drive source 22 to drive the anti-collision body 31 to rise and fall, thus reducing the power consumption and operating costs of the guide vehicle.

[0049] Please refer to the following: Figure 3 and Figure 11 The moving mechanism 4 includes two driving components, two main rolling wheels 41, and four auxiliary rolling wheels 42. The two main rolling wheels 41 are symmetrically installed in the middle of both sides of the guide vehicle body 1. The two driving components are correspondingly connected to the two main rolling wheels 41. The four auxiliary rolling wheels 42 are evenly installed at the bottom of the guide vehicle body 1. The driving components can be composed of a drive motor 43, a worm gear 44, and a worm wheel 45. The drive motor 43 is fixedly installed inside the guide vehicle body 1. One end of the worm gear 44 is fixed to the drive end of the drive motor 43. The worm wheel 45 is fixed to one side of the main rolling wheel 41. One end of the worm gear 44 meshes with the worm wheel 45. The drive motor 43 drives the worm gear 44 to rotate, so that the worm wheel 45 can drive the main rolling wheel 41 to rotate. Each of the two main rolling wheels 41 is driven by a separate drive motor 43. Different movement requirements can be achieved by controlling the speed of the drive motor 43.
