[0002] In recent years, the huge volume of passenger and freight transport has put heavy pressure on cargo terminal logistics and airport logistics operations. The traditional airport logistics operation mode that relies on manual driving faces many challenges. The adoption of automated handling operation mode can solve the problems of labor shortage and high labor costs in traditional airport logistics to a certain extent. It is one of the main handling methods for automated material handling in factories and warehouses.

[0003] Existing material handling systems consist of transport devices and trolleys. After goods are received into the warehouse, they can only be retrieved by the combined action of the transport devices and trolleys. The entire system is complex and requires external power to assist the trolleys in storage and retrieval, resulting in low handling efficiency. Furthermore, when removing containers from the trolleys, external force is required to drag the goods, which can cause displacement of heavy items such as containers and damage to their contents.

[0059] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0060] This embodiment provides a conveying system, such as Figure 1 As shown, the conveying system includes a conveying platform 200 and a conveying mobile device 100. The conveying platform 200 is generally located within the freight yard. The conveying mobile device 100 can also be referred to as an Automated Guided Vehicle (AGV), which is specifically a mobile robot that autonomously drives and performs tasks. The conveying mobile device 100 is configured to receive items to be conveyed at the conveying platform 200, or to carry items to be conveyed and transport them to the conveying platform 200. The items to be conveyed are specifically heavy-duty goods or containers.

[0061] For example, when it is necessary to remove the item to be transported from the conveying platform 200, the conveying moving device 100 can move to the position corresponding to the conveying platform 200. After receiving the item to be transported, the conveying moving device 100 drives the item to be transported to move away from the conveying platform 200 until it reaches a preset position and stops to unload.

[0062] When it is necessary to transfer the item to be transported from the preset position, after receiving the item, the conveying moving device 100 drives the item to be transported in the direction of the conveying platform 200 until it moves to the position corresponding to the conveying platform 200. Then the conveying moving device 100 transports the item to be transported to the conveying platform 200.

[0063] The conveying system provided in this embodiment has a simple structure, is easy and flexible to set up, and is convenient for customers to operate and use, thanks to the cooperation between the conveying platform 200 and the conveying mobile device 100.

[0064] It is understood that for the conveying of the items to be conveyed between the conveying platform 200 and the conveying mobile device 100, the items can be conveyed away from the conveying platform 200 by a conveyor fixedly installed on the conveying platform 200, or by a conveyor located on one side of the conveying platform 200 and separately installed from the conveying platform 200, or by manual handling. This embodiment does not limit the conveying method; as long as the items to be conveyed on the conveying platform 200 can be conveyed to the conveying mobile device 100, it is within the protection scope of this embodiment.

[0065] In one embodiment, such as Figure 2 As shown, a docking position sensor 11 is installed on the vehicle body 1 to detect the position of the conveyor platform 200.

[0066] Specifically, such as Figure 2 As shown, the conveying mobile device 100 provided in this embodiment includes a vehicle body 1, a conveying mechanism 2, and a traveling mechanism 3. The conveying mechanism 2 is located on one side of the vehicle body 1 along a first direction. The conveying mechanism 2 includes a conveying drive source (not shown in the figure) and a roller 21. The conveying drive source can be a motor. The conveying drive source is disposed on the vehicle body 1. The output end of the conveying drive source is connected to the roller 21. The roller 21 is used to carry the item to be conveyed. The conveying drive source can drive the roller 21 to rotate relative to the vehicle body 1. The traveling mechanism 3 is disposed on the other side of the vehicle body 1 along the first direction and is used to drive the vehicle body 1 to move.

[0067] The shape of the vehicle body 1 is similar to a cuboid structure. The first direction is the height direction of the vehicle body 1, which is marked by D1. The second direction is the width direction of the vehicle body 1, which is marked by D2. The third direction is the length direction of the vehicle body 1, and the third direction is also the axial direction of the roller 21, which is marked by D3. The first direction, the second direction and the third direction are perpendicular to each other.

[0068] For example, when roller 21 initially contacts the item to be conveyed, the conveying drive source drives roller 21 to rotate. Roller 21 receives the item and can drive it to move in a third direction, thus realizing the conveying process. Using this roller 21 conveying method, heavier items can be directly placed on the conveying platform 200, reducing the labor intensity of manual handling and ensuring the safety of the items inside the item.

[0069] The embodiment includes multiple rollers 21, which are arranged in parallel at intervals along a third direction. There is at least one conveying drive source, which can be multiple conveying drive sources connected to multiple rollers 21, each driving its corresponding roller 21 to rotate, allowing individual adjustment of the rotation speed of each roller 21. Alternatively, one conveying drive source can drive multiple rollers 21 to rotate via a transmission assembly, ensuring the synchronization of the rotation of the multiple rollers 21. This embodiment does not limit the transmission method between the conveying drive source and the rollers 21.

[0070] After the item to be transported is completely placed on the vehicle body 1, the traveling mechanism 3 drives the vehicle body 1 to move, and moves the item to be transported to a preset position, realizing the long-distance transport process of the item. At the same time, the traveling mechanism 3 and the conveying mechanism 2 are respectively set on both sides of the vehicle body 1 along the first direction, so the two processes of handling and transporting do not affect each other, improving the reliability of use.

[0071] The conveying mobile device 100 provided in this embodiment adopts the roller conveying method 21, which can travel in all directions without the need for external power equipment, thereby improving conveying efficiency and safety, and facilitating the handling of baggage containers in freight yards and airports.

[0072] In one embodiment, such as Figure 3 As shown, the conveying and moving device 100 also includes a first position sensor 4 and a control mechanism 6. The first position sensor 4 is disposed on the vehicle body 1 and is used to detect the environment around the vehicle body 1, such as whether there are obstacles around the vehicle body 1. The control mechanism 6 is electrically connected to the first position sensor 4 and the walking mechanism 3. The first position sensor 4 can be optionally equipped with an emergency stop switch. If there are obstacles around the vehicle body 1, the first position sensor 4 transmits the signal to the control mechanism 6, and the control mechanism 6 controls the walking mechanism 3 to stop moving to avoid the vehicle body 1 from colliding with the obstacles.

[0073] Specifically, there are multiple first position sensors 4, for example, four first position sensors 4 are respectively set at the four corners of the vehicle body 1. The four first position sensors 4 are set on the vehicle body 1 along the circumference of the vehicle body 1, which is conducive to more accurate detection of the situation around the vehicle body 1.

[0074] Because multiple first position sensors 4 are mounted on the vehicle body 1, they can only detect the situation around the vehicle body 1 in the planes of the second and third directions, but cannot detect the situation in three-dimensional space. Therefore, as... Figures 2-4 As shown, the conveying mobile device 100 also includes a laser detection component 5, which includes a bracket 51 and a laser radar 52. One end of the bracket 51 is disposed on the vehicle body 1 along the first direction, and the other end is disposed on the laser radar 52.

[0075] For example, the bracket 51 extends along the first direction and has a certain height. The lidar 52 is located at the top of the bracket 51 along the first direction, so that the height of the lidar 52 along the first direction is higher than the height of the first position sensor 4. The lidar 52 can scan the road conditions around the vehicle body 1 from above and realize three-dimensional spatial detection.

[0076] Specifically, the lidar 52, by emitting a laser beam and receiving reflected light, can measure the distance between the vehicle body 1 and its surrounding environment in real time. Using the environmental information provided by the lidar 52, it can perceive the position and shape of obstacles around the vehicle body 1 in real time and generate a high-precision environmental map. The control mechanism 6 is electrically connected to the lidar 52. If there are obstacles around the vehicle body 1, the lidar 52 transmits the signal to the control mechanism 6. The control mechanism 6 uses this data for autonomous navigation, determining the position of the vehicle body 1 on the map—that is, simultaneous localization and mapping. Based on this data, it dynamically plans the optimal path. The control mechanism 6 controls the walking mechanism 3 to avoid obstacles, ensuring efficient and safe driving; or, the control mechanism 6 controls the walking mechanism 3 to stop moving, preventing the vehicle body 1 from colliding with obstacles. This navigation method enables the vehicle body 1 to drive autonomously in complex environments without relying on preset tracks or magnetic strips.

[0077] In addition, a retaining edge 105 is provided around the vehicle body 1 to reduce the impact of surrounding obstacles on the vehicle body 1.

[0078] In one embodiment, such as Figure 3 As shown, the conveying mobile device 100 also includes an antenna 8, which is mounted on the bracket 51. The control mechanism 6 is electrically connected to the antenna 8, facilitating wireless communication between the control mechanism 6 and other electronic devices.

[0079] In one embodiment, the conveying device 100 further includes an alarm component 9, which is disposed on the bracket 51, and a control mechanism 6 is electrically connected to the alarm component 9. The control mechanism 6 is used to control the alarm component 9 to sound an alarm.

[0080] For example, when the lidar 52 detects obstacles in the vehicle 1's driving path or surrounding environment, if the control mechanism 6 determines that there is a potential collision risk, the control mechanism 6 controls the alarm component 9 to issue an alarm in a timely manner, or controls the walking mechanism 3 to automatically decelerate and stop. This configuration provides real-time obstacle avoidance, improving the driving safety of the vehicle 1 in complex environments.

[0081] Specifically, the alarm component 9 includes a fault indicator light 91, which is mounted on the bracket 51. When a fault occurs, the control mechanism 6 controls the fault indicator light 91 to light up, and the fault indicator light 91 emits a red light to prompt the operator to check and repair it.

[0082] Specifically, the alarm component 9 also includes an audible and visual alarm 92, which is mounted on the bracket 51. When a malfunction occurs, the control mechanism 6 controls the audible and visual alarm 92 to light up and emit a yellow light to prompt the operator to inspect and repair it.

[0083] Specifically, the alarm component 9 also includes a buzzer 93, which is mounted on the bracket 51. When a malfunction occurs, the control mechanism 6 controls the buzzer 93 to emit an alarm sound to prompt the operator to inspect and repair it.

[0084] In one embodiment, the control mechanism 6 includes a display screen 61, which is an automated display touch screen. The display screen 61 is equipped with a running mode switch 62, a task cancellation button 63, a confirmation button 64, a power indicator light 65, a position indicator light 66, and a power off button 67, etc. The operator can directly operate the display screen 61, which is convenient.

[0085] In one embodiment, such as Figure 5 As shown, the conveying and moving device 100 also includes a second position sensor 10, which is disposed on the vehicle body 1 and corresponding to the roller 21, for detecting the position of the item to be conveyed. The control mechanism 6 is electrically connected to the second position sensor 10.

[0086] When the second position sensor 10 detects the item to be conveyed, it triggers the second position sensor 10 and transmits the position limit signal to the control mechanism 6. The control mechanism 6 controls the conveying drive source of the conveying mechanism 2 to shut off, so that the roller 21 stops rotating.

[0087] For example, there are multiple second position sensors 10, which are disposed on both sides of the roller 21 along the second direction and / or the third direction to improve the detection accuracy of the conveyed item to be detected.

[0088] In one embodiment, such as Figure 2 As shown, the conveying moving device 100 also includes a limiting component 7, which is disposed on the vehicle body 1 and located on at least one side of the conveying mechanism 2 along the second direction. It is used to limit the conveyed part and prevent the conveyed part from easily falling off the vehicle body 1 when the roller 21 is continuously rotating.

[0089] For example, there are two limiting components 7, which are respectively disposed on both sides of the conveying mechanism 2 along the second direction, for limiting the conveyed part on both sides along the second direction.

[0090] Specifically, the limiting component 7 includes a blocking member 71 and a blocking drive source (not shown in the figure). The blocking member 71 may be a baffle, and is used to limit the part to be conveyed. The blocking drive source may be a lifting cylinder. The blocking drive source is disposed on the vehicle body 1, and its output end is connected to the blocking member 71. The blocking drive source can drive the blocking member 71 to move along a first direction.

[0091] For example, when the conveying drive source drives the roller 21 to rotate and moves the conveyed item, the blocking drive source can drive the blocking member 71 to move along the first direction and toward the roller 21. The blocking member 71 is located above the roller 21 along the first direction, that is, the blocking member 71 extends beyond the roller 21 to block the conveyed item and prevent it from falling off the vehicle body 1. When the conveyed item on the roller 21 needs to be transferred from the roller 21 to a preset position, the blocking drive source can drive the blocking member 71 to move along the first direction and away from the roller 21. The blocking member 71 is located below the roller 21 along the first direction to avoid the conveyed item and ensure that the conveyed item is transferred from the roller 21 to the preset position.

[0092] In one embodiment, such as Figure 2 As shown, the limiting component 7 also includes two third position sensors 73. The third position sensors 73 are disposed on the vehicle body 1 and are disposed corresponding to the blocking member 71. One of the third position sensors 73 is used to detect the upper limit position of the blocking member 71 along the first direction, and the other third position sensor 73 is used to detect the lower limit position of the blocking member 71 along the first direction.

[0093] By setting two third position sensors 73, the upper limit position and lower limit position of the blocking member 71 along the first direction can be detected respectively, which can limit the blocking member 71 to a reasonable range, avoid the blocking member 71 extending too high or too low, and improve the accuracy of the limit.

[0094] The control mechanism 6 is electrically connected to the blocking drive source and the third position sensor 73. The third sensor transmits the position signal of the blocking component 71 to the control mechanism 6, and the control mechanism 6 controls the blocking drive source to start or stop.

[0095] In one embodiment, such as Figure 6 As shown, the vehicle body 1 is provided with heat dissipation holes 104 to dissipate heat from inside the vehicle body 1 and prevent performance from being affected by excessively high operating temperature. The vehicle body 1 is also provided with a brush plate 103. The brush plate 103 is provided with copper contacts. After the external charging device is connected to the brush plate 103, the external charging device makes contact with the copper contacts of the brush plate 103 to start the charging function.

[0096] In one embodiment, such as Figures 7-8As shown, the walking mechanism 3 includes walking wheels 31 and steering wheels 32. The walking wheels 31 are rotatably connected to the vehicle body 1. For example, there are four walking wheels 31, which are rotatably arranged at the four corners of the vehicle body 1 to improve the walking stability and balance of the vehicle body 1. The steering wheels 32 are rotatably arranged relative to the vehicle body 1 and are wheels that integrate driving and steering functions. The main body of the steering wheel 32 is usually made of rubber, polyurethane, or other wear-resistant materials. The design of the steering wheel 32 needs to consider load-bearing capacity, friction coefficient, and wear resistance. The number of steering wheels 32 can be selected as two. The two steering wheels 32 can be arranged on both sides of the vehicle body 1 along the second direction or on both sides of the third direction, using a dual-steering wheel 32 drive method to ensure sufficient power and smooth operation.

[0097] Specifically, the walking mechanism 3 also includes a drive motor (not shown in the figure) and a steering mechanism (not shown in the figure). Depending on the application scenario, the drive motor can be a DC motor, an AC motor, or a servo motor. The output end of the drive motor is connected to the steering wheel 32, and the drive motor can drive the steering wheel 32 to rotate, providing power to the vehicle body 1. The steering mechanism includes gear transmission, worm gear transmission, or direct motor drive of the steering shaft, used to adjust the steering angle of the steering wheel 32. In this way, the steering wheel 32 integrates the driving and steering functions into one unit, reducing the complexity and space occupation of the vehicle body 1.

[0098] The control mechanism 6 is electrically connected to the drive motor and the steering mechanism, enabling the conveying mobile device 100 to travel in all directions and to move, turn, and stop.

[0099] In one embodiment, such as Figure 8 As shown, the walking mechanism also includes a pressure adjustment structure 33, which is disposed between the vehicle body 1 and the steering wheel 32, and is used to adjust the position of the steering wheel 32 along the first direction. Depending on the smoothness of the road surface, the pressure adjustment structure 33 can adjust the steering wheel 32 in a timely manner to ensure that the steering wheel 32 has sufficient grip, thereby ensuring driving stability.

[0100] Specifically, the vehicle body 1 includes a main body 101 and a frame 102. The frame 102 is located below the main body 101 along a first direction. The running wheels 31 are rotatably connected to the main body 101, and the steering wheels 32 are rotatably connected to the frame 102.

[0101] like Figure 7As shown, the pressure adjustment structure 33 includes a support frame 331 and a buffer 332. The support frame 331 is located on the side of the main body 101 away from the frame 102. One end of the buffer 332 is connected to the support frame 331, and the other end is connected to the frame 102. The buffer 332 can be a spring. The buffer 332 has sufficient strength and rigidity to withstand the weight of the vehicle body 1 and the impact force during driving, so that the steering wheel 32 maintains sufficient friction with the ground. Even when there are bumps or potholes on the ground, the steering wheel 32 will not fluctuate significantly relative to the ground, resulting in good driving stability.

[0102] In one embodiment, the transport mobile device 100 further includes a lifting mechanism (not shown in the figure), which is connected to the vehicle body 1 and can drive the vehicle body 1 to move in a first direction.

[0103] When the traveling wheel 31 or the steering wheel 32 is damaged and needs repair, the lifting mechanism can be used to adjust the position of the vehicle body 1 along the first direction, making it convenient to repair or replace the traveling wheel 31 or the steering wheel 32.
