Description

Technical Field

[0001] This manual relates to the field of flight case technology, and in particular to a smart flight case specifically designed for robots that is easy to store and stack in warehouses. Background Technology

[0002] With the rapid development of robotics technology, various service robots, inspection robots, and delivery robots are widely used in warehousing and logistics, commercial services, and industrial inspection. When robots are not in operation or need to be transported over long distances, they usually need to be stored in dedicated flight cases or shipping containers to ensure their safety, prevent them from being bumped or knocked, and facilitate centralized management.

[0003] Currently, most robot flight cases on the market are static storage designs, typically consisting of a rigid box and an openable top cover or side door. These cases often require manual handling or assistance to move the robot in and out, resulting in low automation and inefficient operation. Furthermore, when multiple flight cases need to be stacked vertically in a warehouse to save space, the lack of effective securing mechanisms on the casters at the bottom of the cases makes them prone to sliding, shifting, or even tipping over, posing safety hazards and hindering stable, organized, high-density warehousing. Summary of the Invention

[0004] This specification provides one or more embodiments of a robot-specific intelligent flight case that facilitates warehouse storage and stacking, characterized in that it includes:

[0005] The main housing is equipped with multiple casters at its lower end.

[0006] The side box cover is hinged to one side of the main box body at its lower end. The main box body and the side box cover together form a box body with an opening at the top. When the side box cover is opened, it forms an inclined surface with the ground for the robot to move on.

[0007] The receiving component is disposed in the main box and one end is rotatably connected to the lower end of the side box cover. The receiving component is driven by a first power source to realize the opening and closing of the side box cover and the lifting and lowering of the robot.

[0008] The stacking and fixing components include a top cover and a limiting mechanism. The top cover is used to seal the box formed by the main box body and the side box cover. The top cover is provided with multiple slots corresponding to the casters. When the casters are embedded in the corresponding slots, the limiting mechanism can extend into the slots in the horizontal direction and abut against the casters under the drive of the second power source, thereby restricting the casters in the slots.

[0009] The control system is located inside the main housing. The control system includes a signal receiving module, a central processing module, and a motor drive module. The signal receiving module can receive signals emitted by the robot, which are then processed by the central processing module to control the first power source drive.

[0010] In some embodiments, a first inner liner is fixed to the side wall of the main housing, a second inner liner is fixed to the bottom wall of the main housing, a third inner liner is fixed to the inner wall of the side cover, and a fourth inner liner is fixed to the upper side wall of the top cover.

[0011] In some embodiments, the receiving assembly includes a receiving plate and a connecting plate. One end of the connecting plate is hinged to the inner wall of the main box, and the other end is rotatably connected to the receiving plate. The other end of the receiving plate is rotatably connected to the lower end of the side box cover. The upper surface of the second liner has a downwardly recessed storage groove for accommodating the receiving plate. A gap is formed between the lower end of the first liner and the bottom wall of the storage groove. When the receiving plate abuts against the bottom wall of the storage groove, the connecting plate is vertically located within the gap between the first liner and the storage groove. The side box cover is vertically attached to one side of the main box and together with it to form a box with an upper opening. The receiving plate and the connecting plate are perpendicular to each other.

[0012] In some embodiments, the receiving assembly further includes a threaded sleeve, a screw, and a hinge seat. A first cavity that is recessed downward and vertically through is provided on the bottom wall of the receiving groove. The lower end of the hinge seat is rotatably connected to the bottom wall of the main housing. The upper end of the threaded sleeve is hinged to the lower end face of the receiving plate. The screw is threadedly connected to the threaded sleeve. The first power source is a first motor fixed on the hinge seat. One end of the screw is fixedly connected to the output shaft of the first motor. When the screw rotates, the threaded sleeve moves along the screw in a direction away from the hinge seat. Then, the threaded sleeve moves the receiving plate upward and closer to the side cover.

[0013] In some embodiments, sliding sleeves are fixed on both the left and right sides of the threaded sleeve, and two guide ribs parallel to the threaded sleeve are fixed on the hinge seat, with the sliding sleeves slidably connected to the guide ribs.

[0014] In some embodiments, the top cover has multiple through slots corresponding to the slots, the slots are fixed in the corresponding through slots, a housing is provided on one side of the slot, a second cavity for accommodating the housing is provided on the fourth inner liner, a through hole communicating with the housing is provided on the side wall of the slot, a slider is slidably connected in the housing, a limiting block is fixed on the side of the slider near the slot, a rack is fixed on the side of the slider away from the slot, a fixing box is fixed on the housing, the second power source is a second motor in the fixing box, the fixing box is fixed on the upper side wall of the top cover, a gear shaft extending into the housing is fixed at the end of the output shaft of the second motor, the gear shaft is rotatably connected to the housing, and a gear meshing with the rack is fixed at the end of the gear shaft.

[0015] In some embodiments, four omnidirectional wheels are provided and arranged in a rectangular pattern, the four slots are arranged in pairs, the housing is provided with two slots located on the left and right sides respectively, two sliders are symmetrically arranged in the same housing, there is a gap between the side of the slider and the side wall of the housing, and the end of the rack can be accommodated in the gap between the slider and the housing.

[0016] In some embodiments, the side of the limiting block near the slot is an arc surface, and the limiting block can extend into the slot under the drive of the gear and abut against the surface of the roller on the universal wheel.

[0017] Beneficial effects:

[0018] 1. The first motor drives the screw to rotate, causing the threaded sleeve to move along its axis towards the side cover, thereby pushing the receiving plate upward and forward. This causes the side cover to rotate with its lower end as the center until it forms an incline with the ground, so that the robot can move along the incline formed by the side cover to the receiving plate.

[0019] 2. The screw reverses, causing the receiving plate to carry the robot into the main box. The receiving plate moves until it comes into contact with the storage slot. The side box cover rotates with the movement of the receiving plate until it surrounds the main box to form a box. After the top cover is closed, the side box cover, the main box and the top cover are locked together by the butterfly lock.

[0020] 3. When multiple flight cases are stacked vertically, the casters are stored in the slots of the lower flight case. The second motor drives the gear to rotate, which causes the limiting block to extend into the slot and abut against the outer circumference of the roller on the caster, thereby restricting the caster within the slot and ensuring the stability of the flight cases when stacked.

[0036] To more clearly illustrate the technical solutions of the embodiments in this specification, the embodiments will be described in detail below with reference to the accompanying drawings. Obviously, the content described below are some examples or embodiments of this specification. For those skilled in the art, without creative effort, the technical solutions or means disclosed in this specification can be applied to other scenarios based on this technical content.

[0037] It should be understood that the terms "system," "device," "unit," and / or "module" used in this specification are a method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0038] Unless otherwise specified, the technical terms used to describe components, elements, etc. in this specification are not singular but may include plural. Generally speaking, terms such as "comprising" or "including" only indicate that clearly identified steps, elements, or components are included, and these steps, elements, and components do not constitute an exclusive list, as the described method or apparatus may also include other steps or components.

[0039] This specification uses flowcharts to illustrate the operational steps performed by the apparatus or system of related embodiments. However, unless otherwise specified, the order in which these steps are described should not be construed as a limitation on the order of execution. Those skilled in the art can adjust the order of these steps based on the knowledge and information conveyed by the embodiments in this specification. Such adjustments include, but are not limited to, reversing the order of steps, merging multiple steps, and splitting a step.

[0040] With the rapid development of robotics technology, various service robots, inspection robots, and delivery robots are widely used in warehousing and logistics, commercial services, and industrial inspection. When robots are not in operation or need to be transported over long distances, they usually need to be stored in dedicated flight cases or shipping containers to ensure their safety, prevent them from being bumped or knocked, and facilitate centralized management.

[0041] Currently, most robot flight cases on the market are static storage designs, typically consisting of a rigid box and an openable top cover or side door. These cases often require manual handling or assistance to move the robot in and out, resulting in low automation and inefficient operation. Furthermore, when multiple flight cases need to be stacked vertically in a warehouse to save space, the lack of effective securing mechanisms on the casters at the bottom of the cases makes them prone to sliding, shifting, or even tipping over, posing safety hazards and hindering stable, organized, high-density warehousing.

[0042] Large e-commerce warehouses, smart manufacturing plants, or logistics sorting centers deploy a large number of AGVs (Automated Guided Vehicles), handling robots, or sorting robots. This intelligent flight case can serve as a "dedicated parking space" and "mobile base station" for robots. During non-operational periods or charging periods, robots can autonomously return and drive into the flight case; multiple flight cases carrying robots can be easily moved using their casters, and can be safely and stably stacked vertically using slots and limiting mechanisms on the top cover, greatly saving warehouse space and enabling high-density, modular parking and management of robot fleets.

[0043] Therefore, some embodiments of this specification propose a robot-specific intelligent flight case that facilitates storage and stacking, including a main body 10, a side cover 20, a receiving component, a stacking and fixing component, and a control system. The main body 10 is equipped with multiple casters 40 at its lower end and a handle for moving the flight case. The main body 10 is made of high-strength engineering plastic or metal, and its internal structure has reinforcing ribs to improve load-bearing capacity and durability. The lower end of the side cover 20 is hinged to one side of the main body 10. The main body 10 and the side cover 20 together form a case with an open top. When unfolded, the cover 20 forms an inclined angle with the ground, preferably 15°-30°, to create a slope for the robot to enter and exit smoothly. The upper edge of the side cover 20 is fixedly connected to the top cover 30, and the side cover 20 is fixedly connected to the main body 10 by a butterfly lock. The receiving component is set inside the main body 10 and one end is rotatably connected to the lower end of the side cover 20. The receiving component is driven by a first power source, thereby realizing the opening and closing of the side cover 20 and the lifting and lowering of the robot. The stacking and fixing component includes the top cover 30 and a limiting mechanism. The top cover 30 is used to seal the area formed by the main body 10 and the side cover 20. The housing, top cover 30, is provided with multiple slots 31 corresponding to the casters 40. When the casters 40 are embedded in the corresponding slots 31, the limiting mechanism, driven by the second power source, can extend horizontally into the slots 31 and abut against the casters 40, thereby restricting the casters 40 within the slots 31. In this embodiment, two switches for controlling the second power source can be provided on the top cover 30. The switches are located on the side of the top cover 30. Switch one controls the second power source to rotate forward to lock the casters 40, and switch two controls the second power source to rotate in reverse to release the casters 40. Control system The control system, located inside the main housing 10, includes a signal receiving module, a central processing module, and a motor drive module. The signal receiving module can be a wireless communication module (such as Wi-Fi, Bluetooth, or a radio frequency module) to receive control signals (such as return-to-hospital signals, exit-to-hospital signals, etc.) emitted by the robot. After receiving the signals, the central processing module (such as a microcontroller MCU) controls the start, stop, and direction of the first and second power sources according to a preset program. The aforementioned switches are electrically connected to the control system and can also be integrated into the user interface of the control system to realize a dual mode of manual and automatic control.

[0044] Specifically, a first inner liner 11 is fixed on the side wall of the main housing 10, a second inner liner 12 is fixed on the bottom wall of the main housing 10, a third inner liner 21 is fixed on the inner wall of the side cover 20, and a fourth inner liner 32 is fixed on the upper side wall of the top cover 30. The inner liner material can be a cushioning material (such as EVA foam, rubber or silicone) to protect the robot from collisions and improve the sealing and shock absorption performance of the housing.

[0045] Specifically, the receiving component includes a receiving plate 22 and a connecting plate 26. One end of the connecting plate 26 is hinged to the inner wall of the main box 10, and the other end is rotatably connected to the receiving plate 22. The other end of the receiving plate 22 is rotatably connected to the lower end of the side box cover 20. The upper surface of the second inner lining 12 has a downwardly recessed storage groove 14 for accommodating the receiving plate 22. A gap is formed between the lower end of the first inner lining 11 and the bottom wall of the storage groove 14. When the receiving plate 22 abuts against the bottom wall of the storage groove 14, the connecting plate 26 is vertically located in the gap between the first inner lining 11 and the storage groove 14. The side box cover 20 is vertically attached to one side of the main box 10 and surrounds it to form a box with an open top. The receiving plate 22 and the connecting plate 26 are perpendicular to each other.

[0046] Specifically, the receiving assembly also includes a threaded sleeve 27, a screw 25, and a hinge seat 23. A first cavity 15 is recessed downwards and vertically through the bottom wall of the receiving groove 14. The lower end of the hinge seat 23 is rotatably connected to the bottom wall of the main housing 10. The upper end of the threaded sleeve 27 is hinged to the lower end face of the receiving plate 22. The screw 25 is threadedly connected to the threaded sleeve 27. The first power source is a first motor 24 fixed on the hinge seat 23. One end of the screw 25 is fixedly connected to the output shaft of the first motor 24 through a coupling. When the screw 25 rotates, the threaded sleeve 27 moves along the screw 25 away from the hinge seat 23. The threaded sleeve 27 then pushes the receiving plate 22 upwards and towards the side cover 20.

[0047] Specifically, sliding sleeves 28 are fixed on both sides of the threaded sleeve 27, and two guide ribs 29 parallel to the threaded sleeve 27 are fixed on the hinge seat 23. The sliding sleeve 28 is slidably connected to the guide ribs 29. The setting of the guide ribs 29 increases the strength between the screw 25 and the threaded sleeve 27 and improves the stability of the relative sliding between the screw 25 and the threaded sleeve 27.

[0048] Specifically, the top cover 30 has multiple through slots corresponding to the slots 31. The slots 31 are fixed in the corresponding through slots. A housing 34 is provided on one side of the slots 31. A second cavity 35 for accommodating the housing 34 is provided on the fourth inner liner 32. A through hole 33 communicating with the housing 34 is provided on the side wall of the slots 31. A slider 310 is slidably connected inside the housing 34. A limiting block 312 is fixed on the side of the slider 310 near the slots 31. A rack 311 is fixed on the side of the slider 310 away from the slots 31. A fixing box 36 is fixed on the housing 34. The second power source is a second motor 37 inside the fixing box 36. The fixing box 36 is fixed on the upper side wall of the top cover 30. A gear shaft 39 extending into the housing 34 is fixed at the end of the output shaft of the second motor 37. The gear shaft 39 is rotatably connected to the housing 34. A gear 38 meshing with the rack 311 is fixed at the end of the gear shaft 39.

[0049] Specifically, there are four casters 40 arranged in a rectangular shape, four slots 31 are arranged in pairs, and the housing 34 has two slots 31 located on the left and right sides respectively. There are two sliders 310 symmetrically arranged in the same housing 34. There is a gap between the side of the slider 310 and the side wall of the housing 34. The end of the rack 311 can be accommodated in the gap between the slider 310 and the housing 34.

[0050] Specifically, the side of the limiting block 312 near the slot 31 is an arc surface. Driven by the gear 38, the limiting block 312 can extend into the slot 31 and abut against the surface of the roller on the universal wheel 40.

[0051] Initially, the robot is stored in a flight case. The main body 10, side cover 20, and top cover 30 are fixed together by butterfly locks. When multiple flight cases are stacked, the casters 40 are embedded in the slots 31 on the lower side. When the switch on the top cover 30 is pressed, the central processing module in the control system receives the signal and controls the second motor 37 to start rotating forward, thereby driving the rack 311 to move. This drives the limit block 312 to move closer to the slot 31 until the limit block 312 abuts against the roller on the caster 40, thereby restricting the caster 40 within the slot 31 and ensuring the stability when multiple flight cases are stacked.

[0052] When it is necessary to remove the robot from the flight case, press the second switch on the top cover 30, the second motor 37 will be reversed, and the limit block 312 will move in the opposite direction to reset into the housing 34, so as to separate the two adjacent flight cases.

[0053] After placing a single flight case on the ground, open the butterfly latch between the top cover 30 and the side cover 20, and flip the top cover 30 open while simultaneously opening the butterfly latch between the main body 10 and the side cover 20.

[0054] When the robot is started, it sends an "exit" command to the signal receiving module in the control system via wireless signal. After receiving the command, the central processing module controls the first motor 24 to rotate in the forward direction, which causes the screw 25 to rotate in the forward direction. Then the threaded sleeve 27 moves away from the first motor 24 along the axis of the screw 25. The threaded sleeve 27 pushes the receiving plate 22 upward and towards the side box cover 20.

[0055] During this process, the side box cover 20 is pushed by the receiving plate 22 and flips away from the main box 10 with the lower end of the side box cover 20 as the center until the upper end of the side box cover 20 touches the ground, so that the side box cover 20 forms a slope.

[0056] At the same time, the receiving plate 22 and the connecting plate 26 rotate to be level with each other. The receiving plate 22 pushes the robot upward to be level with the upper end of the ramp-shaped receiving plate 22. After the robot starts, it can autonomously travel from the flight case to the ground along the ramp-shaped receiving plate 22 without manual handling.

[0057] After the robot has completely left the flight case, it can send a "close the case" signal to the control system. The central processing module controls the first motor 24 to reverse, so that the side case cover 20 and the receiving plate 22 are reset, and the case is restored to the closed state.

[0058] When the robot needs to return to its cargo container, it sends a "return to container" signal. The control system then controls the side container cover 20 to unfold again, forming a ramp. The robot travels along the ramp to the receiving plate 22. Subsequently, the robot sends a "close container" signal, and the control system controls the side container cover 20 to close. The operator locks the butterfly latch and closes the top cover 30, completing the storage and securing of the robot.

[0059] To achieve automated interaction between the robot and the intelligent flight case, this embodiment further details the specific implementation methods of the communication architecture, signal processing, and control logic, including the following:

[0060] I. Communication Hardware Architecture:

[0061] The robot integrates a first wireless communication module (such as a Wi-Fi module, Bluetooth module, or Zigbee module) to send control commands and status signals. The flight case's control system includes a matching second wireless communication module (i.e., a signal receiving module), a central processing module (such as an STM32 series microcontroller, ARM processor, etc.), and a motor drive circuit.

[0062] The central processing module is connected to the drivers of the first motor 24 and the second motor 37 via GPIO pins or communication interfaces (such as UART, I2C) to output PWM signals or direction / enable signals to control the start, stop, direction and speed of the motors. The signal receiving module is connected to the central processing module via serial communication to transmit the received robot instructions in real time.

[0063] II. Signal Definition and Interaction Protocol

[0064] The robot communicates with the flight case control system using a predefined instruction set to ensure reliable interaction. Instructions can be encoded as simple strings or binary data packets and transmitted via a wireless channel. Core instructions include, but are not limited to: EXIT_REQUEST: The robot requests to leave the warehouse; ENTER_REQUEST: The robot requests to return to the warehouse; CLOSE_REQUEST: The robot requests that the hatch (side box cover 20) be closed. STATUS_QUERY: The robot queries the status of the flight case (such as whether the side cover 20 is open, the position of the receiving plate 22, etc.). ACK_SUCCESS: The flight case confirmation command was executed successfully; ACK_FAILURE: The flight box command failed to execute and an error code was provided.

[0065] III. Detailed description of the control process, specifically including: S3.1 Outbound Process: A1. The robot sends the EXIT_REQUEST command to the flight box via its first wireless communication module; A2. The signal receiving module of the flight case receives the instruction and transmits it to the central processing module; A3. The central processing module performs instruction verification and parsing, and then executes the following sequence of actions: A3.1 Control the second motor 37 to reverse (if it is in the stacking lock state) to retract the limit block 312; A3.2 Control the first motor 24 to start in the forward direction, drive the screw 25 to rotate, push the receiving plate 22 to rise and move outward through the threaded sleeve 27, and at the same time the side box cover 20 unfolds synchronously; A3.3. The position sensor (such as an angle sensor or a limit switch) installed in the main body 10 is used to detect whether the side cover 20 has reached the preset angle of full opening (such as a 25° angle with the ground) and whether the support plate 22 has reached the highest position. A3.4 When the sensor sends a signal indicating that it is in position, the central processing module controls the first motor 24 to stop and drives the audible and visual prompt (such as a buzzer or LED) to issue a "ready" prompt. A3.5 The central processing module sends an ACK_SUCCESS signal to the robot through the signal receiving module, and may also include status information; A4. After receiving successful confirmation, the robot autonomously drives away from the receiving plate 22 along the formed ramp and completes the exit from the warehouse.

[0066] S3.2, Closing and Reclaiming Procedures: A1. The robot moves to the vicinity of the flight box, aligns itself with the slope, and sends the ENTER_REQUEST command; A2. After receiving the instruction, if the central processing module of the flight case detects that the side case cover 20 is in a closed state, it will automatically start the opening action in the above-mentioned outbound process and send ACK_SUCCESS. A3. After the robot confirms that the ramp has been formed, it drives along the ramp until its weight sensor or vision system confirms that it has completely stopped in the designated area of ​​the receiving plate 22. A4. The robot sends the CLOSE_REQUEST command; A5. The central processing module of the flight case controls the first motor 24 to reverse, pulling the receiving plate 22 back into the storage slot 14, and the side case cover 20 closes simultaneously. A6. After closing in place (confirmed by a magnetic sensor or micro switch located on the hinge or edge of the housing), the central processing module controls the first motor 24 to stop, and can automatically lock through the electric locking tongue in the butterfly latch (not shown in the figure, which is an optional extension); A7. The flight case sends a closing completion confirmation signal to the robot.

[0067] IV. Safety and Anomaly Handling Mechanisms: To ensure system reliability, the following safety logic is integrated into the control system: Timeout protection: If no sensor feedback is received within a preset time (e.g., 30 seconds) for any motor movement, it will automatically stop and send ACK_FAILURE (error code: timeout) to the robot, while triggering a local alarm.

[0068] Status self-check: When the system is powered on, the central processing module automatically checks whether each sensor, motor drive circuit and communication module is normal.

[0069] Double confirmation: For critical actions such as "closing the hatch", after receiving the robot's instruction, a second opportunity for manual confirmation can be provided through the physical button or touch screen on the flight case to prevent accidental operation.

[0070] Emergency stop function: An emergency stop button is provided on the outside of the main body 10 of the flight case. Once triggered, it will immediately cut off the power supply to all motors.

[0071] Through the specific communication protocols, control processes, and security designs described above, those skilled in the art can clearly understand how to build and program the intelligent flight case to achieve collaborative work between the robot, thereby fully realizing the automated warehousing and retrieval functions of the present invention.

[0072] It should be noted that the above description of the system and its modules is for convenience only and should not be construed as limiting this specification to the embodiments described. It is understood that those skilled in the art, after understanding the principles of this system, may arbitrarily combine the various modules without departing from these principles to form subsystems connected to other modules. Alternatively, some modules may be split to obtain more modules or multiple units under a single module. Such modifications are all within the scope of this specification.

[0073] The beneficial effects that the embodiments of this specification may bring include, but are not limited to: 1. The first motor drives the screw to rotate, causing the threaded sleeve to move along its axis towards the side cover, thereby pushing the receiving plate upward and forward. This causes the side cover to rotate with its lower end as the center to form an incline with respect to the ground, so that the robot can move along the incline formed by the side cover onto the receiving plate. 2. The screw reverses, causing the receiving plate to move with the robot into the main box. The receiving plate moves to abut against the storage slot. The side cover rotates with the movement of the receiving plate to surround the main box to form a box. After the top cover is closed, the side cover, the main box, and the top cover are locked together by a butterfly lock. 3. When multiple flight cases are stacked vertically, the casters are stored in the slots of the lower flight case. The second motor drives the gear to rotate, causing the limiting block to extend into the slot and abut against the outer circumference of the roller on the caster, thereby restricting the caster within the slot and ensuring the stability of the flight cases during stacking.
