DETAILED DESCRIPTION

[0019] See Figure 1-5 As shown, the utility model is an intelligent logistics trolley, including a frame 1, a universal movable seat 2 is provided at the bottom of the frame 1, the universal movable seat 2 is connected to the intelligent control terminal, and the intelligent control terminal includes a voice recognition system; a plurality of layers of temporary storage slots 3 are provided on the frame 1 on the side perpendicular to the forward direction, a lifting component 4 is provided on the frame 1, and a rotating platform 5 is provided on the lifting component 4; a linear movable platform 6 for cooperating with the shelf is provided on the rotating platform 5, two grabbing components 7 are symmetrically provided on the linear movable platform 6, and a pushing component 8 is provided at the rear end of the linear movable platform 6.

[0020] The intelligent control terminal receives and recognizes customer voice commands in real time and transmits them to the universal mobile platform, which then moves to the appropriate shelf. The lifting and gripping components work together to retrieve the corresponding express shipment and deliver it to the customer. This automated process significantly improves the speed and accuracy of express delivery, reduces reliance on manual labor, and effectively lowers operating costs.

[0021] The intelligent control terminal includes a multifunctional sensor system, a voice recognition system, and corresponding control components mounted on a frame. The multifunctional sensor system includes a grayscale sensor for automatic tracking, a GM65 barcode and QR code reader for rapid identification and tracking of parcels, and a camera. The specific mounting structure and connection method are common knowledge to those skilled in the art and will not be described in detail here.

[0022] The speech recognition system, based on the Raspberry Pi platform, uses open-source speech recognition libraries (such as SpeechRecognition or the Google Speech API) to capture and interpret user voice commands. It then connects specific commands to actual actions using a pre-trained language model. Recognized commands are then sent to the universal mobile seat via a serial port or network interface, enabling operations such as path planning, obstacle avoidance, and precise positioning.

[0023] The rotating platform is composed of a rotating motor and a platform plate arranged on a lifting assembly. Its specific installation structure and connection method are common knowledge to those skilled in the art and will not be described in detail here.

[0024] In this embodiment, the universal mobile seat 2 includes a base 2a disposed at the bottom of a frame 1. Four drive motors 2b are located at the bottom of base 2a, and Mecanum wheels 2c are connected to the output shafts of each drive motor 2b. Currently, express delivery stations on the market are typically small and contain numerous shelves, resulting in limited interior space. The use of Mecanum wheels enables the universal mobile seat to achieve full range of movement and flexible steering within this confined space, making it suitable for use in most express delivery stations and warehouses.

[0025] In this embodiment, the lifting assembly 4 comprises four first stepper motors 4a vertically mounted on the frame 1. A first lead screw 4c is mounted on the frame 1, connected to the output of the first stepper motor 4a via a bearing 4b. A lifting platform 4d is positioned above the first stepper motor 4a, with a first nut 4e mounted on the sidewall of the lifting platform 4d, corresponding one-to-one with the first lead screw 4c. The synchronized operation of the four stepper motors ensures that the platform remains highly parallel and stable during the lifting process, preventing platform tilt due to motor failure or accumulated errors, as compared to a single-motor drive.

[0026] In this embodiment, the linear motion platform 6 preferably includes a support rail 6a mounted on the rotating platform 5, with a sliding platform 6b mounted on the support rail 6a via a sliding block. A second stepper motor 6c is mounted on the rotating platform 5, with a second screw 6d connected to the output end of the second stepper motor 6c. A second nut 6e is mounted at the bottom of the sliding platform 6b via a shaft seat and engages with the second screw 6d. The support rail elevates the sliding platform, leaving space for the second stepper motor, allowing it to be positioned below the sliding platform, reducing the equipment footprint and facilitating the trolley's access to narrow spaces.

[0027] Preferably, the sliding platform 6b is provided with first side panels 6f on both sides along the forward direction, and a second side panel 6g is provided on the rotating platform 5, opposite the first side panel 6f. The second side panel 6g is provided with a first linear guide 6h, and the first side panel 6f is provided with a sliding seat that cooperates with the first linear guide 6h. Adding the first linear guides on both sides to guide the sliding platform improves its stability and ensures smooth cargo removal.

[0028] In this embodiment, the grabbing assembly 7 preferably includes two second linear guide rails 7a symmetrically arranged on the linear movable platform 6, with a movable cantilever 7b connected to the second linear guide rails 7a via a sliding seat; a third stepper motor 7c is provided at the rear end of the movable cantilever 7b, and a third screw rod 7d is connected to the output end of the third stepper motor 7c. A third nut 7e that cooperates with the third screw rod 7d is provided on the linear movable platform 6 via a shaft seat; a steering gear 7f is provided at the front end of the movable cantilever 7b, and a grabbing claw 7g perpendicular to the movable cantilever 7b is connected to the output end of the steering gear 7f. The grabbing claw is controlled by the steering gear to rotate, and when the grabbing claw is extended, it can avoid the express and reach the back of the express to grab it, and it can make way to avoid interference when the pusher assembly pushes the express.

[0029] Two third stepper motors are used to synchronously provide push and pull power, allowing the two grab hooks to operate independently. This ensures continued retrieval even if one motor fails. The two stepper motors work synchronously to provide greater push and pull force, ensuring stable operation even under heavy loads. This also evenly distributes the load, reducing the burden on individual motors and improving the overall efficiency of the system.

[0030] In this embodiment, the pusher assembly 8 includes a C-shaped mounting base 8a mounted on the linear motion platform 6. Two horizontal gears 8b are mounted on the C-shaped mounting base 8a. A servo motor 8c is also mounted on the C-shaped mounting base 8a and connected to one of the horizontal gears 8b. A linkage rod 8d is integrally formed on each of the horizontal gears 8b. A telescopic linkage rod assembly 8e is connected to the free end of the linkage rod 8d. A pusher plate 8f is attached to the free end of the telescopic linkage rod assembly 8e. The use of a telescopic linkage rod assembly increases thrust without excessively high pushing speeds, ensuring the smooth ejection of heavy parcels while preventing the rapid ejection of lighter parcels due to excessive thrust, which could cause damage or injury to customers.

[0031] During operation, after the customer inputs the corresponding express information through voice, the intelligent control terminal sends the recognized instructions to the four drive motors on the universal mobile seat to control the frame to move to the corresponding side of the express shelf. After the lifting platform moves to the shelf layer where the express is located, the sliding platform extends close to the shelf, and the mobile cantilever extends to allow the grabbing claw to reach the back of the express. After the grabbing hook rotates to cooperate with the express, the mobile cantilever is retracted to pull the express onto the sliding platform.

[0032] After the sliding platform is retracted, it is rotated 90° through the rotating platform and the lifting platform moves so that the sliding platform is opposite to the temporary storage slot. The servo motor drives the telescopic linkage rod group to extend and push the express to the temporary storage slot for storage. When it moves to the customer's pickup area, the express is taken down and pushed to the customer.

[0033] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
