The voice interaction module, not shown in the diagram, is integrated inside the front compartment 4, including a microphone and speaker, used to receive user voice commands and output voice prompts.

[0054] The interactive unit is electrically connected to the industrial control computer 12 inside the chassis component 1, transmits the received instructions to the industrial control computer 12, and outputs corresponding information according to the instructions of the industrial control computer 12.

[0055] Furthermore, the sensing unit includes a lidar 405 located on the top of the front cabin 4 and a vision camera 418 located at the front of the front cabin 4.

[0056] Specifically, the sensing unit is located on the front cabin 4 and is used to collect environmental information around the robot.

[0057] The LiDAR 405 is used to scan the surrounding environment, build an environmental map, and detect obstacles to achieve autonomous navigation and obstacle avoidance. The visual camera 418 is used to acquire image information from ahead, identify target personnel, room number markers, QR codes, etc., and provide visual support for intelligent navigation.

[0058] The sensing unit is electrically connected to the industrial control computer 12, and transmits the collected environmental information to the industrial control computer 12 for processing in real time.

[0059] Furthermore, the storage space is composed of an upper sealing plate 411 and a lower sealing plate 404 disposed within the front compartment 4;

[0060] The linkage component includes a drive mechanism and a detection mechanism;

[0061] The drive mechanism includes a drive motor 409 and a transmission component that is drive-connected to the drive motor 409. The drive motor 409 is electrically connected to the control unit.

[0062] The detection mechanism is electrically connected to the control unit and is used to detect the opening or closing status of the hatch 401. The detection mechanism is installed on the upper sealing plate 411.

[0063] Specifically, the front compartment 4 is provided with an upper sealing plate 411 and a lower sealing plate 404, forming a storage space between the upper sealing plate 411 and the lower sealing plate 404. The storage space is provided with multiple inner partitions 407, which are spaced apart along the height direction, dividing the storage space into multiple independent storage cavities 408.

[0064] This embodiment provides two storage chambers 408, each with an independently openable hatch 401 at its opening. Each storage chamber 408 corresponds to an independent storage area, which can be used to store different items such as takeout food, housekeeping items, and guest supplies.

[0065] Furthermore, the transmission component includes a rotating shaft 413, a transmission shaft 414, and a rocker arm 406;

[0066] The drive motor 409 is connected to the transmission shaft 414. One end of the rocker arm 406 is inserted into the transmission shaft 414, and the other end of the rocker arm 406 is internally connected to a rotating shaft 413.

[0067] The inner side of the hatch 401 is provided with a rotating connection hole 416, and the rotating shaft 413 is connected to the rotating connection hole 416.

[0068] Furthermore, the detection mechanism includes a micro switch 410 and a trigger linkage 412 mounted on the upper sealing plate 411;

[0069] The inner side of the hatch 401 is provided with a touch connection hole 415;

[0070] The actuating linkage 412 is bent and has a long arm and a short arm. The end of the long arm is connected to the actuating connection hole 415, and the outer side of the short arm is in contact with the micro switch 410.

[0071] The short arm end of the triggering link 412 is rotatably mounted on the upper sealing plate 411;

[0072] The micro switch 410 is triggered by the short arm of the actuation linkage 412 when the hatch 401 is opened or closed, and sends a status signal to the control unit so that the control unit controls the drive motor 409 to stop operating according to the status signal.

[0073] Furthermore, the front cabin 4 is also equipped with a card issuer 417, which is electrically connected to the control unit and is used to issue room cards or vouchers.

[0074] Each hatch is equipped with a linkage component at location 401, which includes a drive mechanism and a detection mechanism.

[0075] like Figure 5 As shown, the drive mechanism includes a drive motor 409 and a transmission component that is drively connected to the drive motor 409. In this embodiment, the transmission component includes a rotating shaft 413, a transmission shaft 414, and a rocker arm 406.

[0076] The drive motor 409 is installed inside the front compartment 4, and its output shaft is connected to the drive shaft 414. One end of the rocker arm 406 is inserted and fixed to the drive shaft 414, and the other end of the rocker arm 406 has a rotating shaft 413 inserted inside. The inner side of the hatch 401 is provided with a rotating connection hole 416, and the rotating shaft 413 is connected to the rotating connection hole 416.

[0077] When the drive motor 409 is activated, it drives the transmission shaft 414 to rotate. The transmission shaft 414 drives the rocker arm 406 to swing, and the rocker arm 406 drives the rotating shaft 413 to rotate, thereby driving the hatch 401 to rotate around the axis of the rotating connection hole 416, realizing the opening or closing of the hatch 401. The drive motor 409 is electrically connected to the industrial control computer 12 and receives control commands from the industrial control computer 12.

[0078] The detection mechanism is installed on the upper cover plate 411 and includes a micro switch 410 and a trigger linkage 412.

[0079] The inner side of the hatch 401 is provided with an actuation connection hole 415. The actuation link 412 is bent and has a long arm and a short arm. The end of the long arm is connected to the actuation connection hole 415, and the outer side of the short arm is in contact with the micro switch 410. The short arm end of the actuation link 412 is rotatably mounted on the upper sealing plate 411 through a rotating shaft structure, so that the actuation link 412 can swing around the rotating shaft.

[0080] The micro switch 410 is mounted on the upper cover plate 411 and electrically connected to the industrial control computer 12. When the hatch 401 opens or closes, the hatch 401 drives the long arm of the actuating linkage 412 to move. The actuating linkage 412 swings around the pivot at the end of its short arm, and its short arm swings accordingly. When the short arm swings, its outer surface contacts or separates from the contacts of the micro switch 410, thereby triggering the micro switch 410.

[0081] After the micro switch 410 is triggered, it sends a status signal to the industrial control computer 12. The industrial control computer 12 determines whether the hatch 401 has been opened or closed based on the status signal, and controls the drive motor 409 to stop moving, ensuring that the hatch 401 stops in time after moving to the correct position to prevent motor overload.

[0082] Furthermore, the control unit includes an industrial computer 12 and a drive unit 11 located within the chassis component 1. The industrial computer 12 is electrically connected to the interaction unit, the sensing unit, and the linkage component, and the drive unit 11 is used to drive the robot to move.

[0083] The front compartment 4 also houses a card issuer 417, which is electrically connected to the industrial control computer 12. The card issuer 417 stores room cards and is used to issue room cards after the user completes identity verification.

[0084] The card dispenser 417 is located at the lower part of the front compartment 4, with its card dispensing port located on the front face of the front compartment 4 for easy card retrieval by the user. After the user completes identity verification by swiping their ID card in the card reader 403 or entering order information in the display screen 402, the industrial control computer 12 controls the card dispenser 417 to dispense the room card for the corresponding room to the card dispensing port.

[0085] The industrial computer 12 is the control core of the robot, and is electrically connected to the interaction unit, the sensing unit, and the linkage components, specifically: the drive motor 409, the micro switch 410, and the card dispenser 417 are electrically connected. The industrial computer 12 receives user instructions from the interaction unit and environmental information from the sensing unit, processes and makes decisions, and sends control commands to each execution component.

[0086] The drive unit 11 includes multiple steering wheels, each integrating a drive motor and a steering mechanism, and is electrically connected to the industrial control computer 12. The industrial control computer 12 plans a path based on the environmental information collected by the sensing unit and sends movement commands to the drive unit 11 to control the robot to move autonomously to the target position.

[0087] This utility model of a luggage handling robot with intelligent navigation function is applied in hotels or business venues, and its working process is as follows:

[0088] When guests require directions, they can speak the command via the voice interaction module or input the target room number via the display screen 402. The interaction unit transmits the command to the industrial control computer 12, which activates the perception unit. The lidar 405 scans the surrounding environment to build a map, and the vision camera 418 acquires image information from ahead and identifies target location markers (such as room number signs and path guidance signs). Based on the perception information, the industrial control computer 12 plans the optimal path and sends movement commands to the drive unit 11, controlling the robot to move autonomously to the target location. During the movement, the perception unit continuously collects environmental information, and the industrial control computer 12 adjusts the path in real time to achieve dynamic obstacle avoidance. At the same time, it outputs directions to the user through the interaction unit: the path guidance map is displayed on the display screen 402, and the voice interaction module broadcasts prompts such as "Turn left ahead" and "Destination reached." After the robot reaches the target location, the industrial control computer 12 notifies the guest "You have arrived at your room" through the interaction unit and stops moving.

[0089] When guests need to store or retrieve items, they verify their identity by entering a verification code on the display screen 402 or by swiping their room card at the card reader 403. The interaction unit transmits the verification information to the industrial control computer 12. After successful verification, the industrial control computer 12 determines the storage compartment 408 that needs to be opened based on the instructions and sends an opening command to the drive motor 409 of the corresponding door 401. The drive motor 409 actuates, driving the door 401 to open via a transmission component. During the opening process, the trigger linkage 412 swings with the door 401. When it swings to the fully open position, it triggers the micro switch 410, which sends a "door open" status signal to the industrial control computer 12. The industrial control computer 12 then controls the drive motor 409 to stop, and the door 401 remains open. After guests take or put in items, they can issue a closing command through the interaction unit, or the system will automatically trigger closing after a preset delay. The industrial computer 12 sends a closing command to the drive motor 409. The drive motor 409 reverses its movement to drive the hatch 401 to close. During the closing process, the linkage 412 is triggered to swing in the opposite direction. When the hatch 401 is closed, the micro switch 410 is triggered again. The micro switch 410 sends a "hatch closed" status signal to the industrial computer 12. The industrial computer 12 controls the drive motor 409 to stop moving and records this access operation.

[0090] When the robot receives multiple task instructions simultaneously, the industrial control computer 12 schedules tasks based on task priority and current location. For example, if it receives an item storage or retrieval task while leading the way, it can complete the leading task first and then execute the storage or retrieval task, or switch tasks according to customer needs, ensuring service efficiency and accuracy in multi-tasking scenarios.

[0091] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
