Description

Technical Field

[0001] The utility model belongs to the field of express delivery vehicles, and in particular relates to an intelligent express delivery vehicle. Background Art

[0002] The rapid development of my country's logistics, express delivery, and e-commerce industries has significantly improved the quality of life for residents. However, this has also brought challenges. Unexpected situations often occur during express delivery, causing significant headaches for both delivery drivers and recipients. Therefore, as a crucial link in the logistics and delivery chain, intelligent and unmanned delivery systems hold immense potential for development.

[0003] Existing smart express delivery vehicles of this type still have some problems and shortcomings. Existing smart express delivery vehicles lack a locker system. In real life, there are two common ways to pick up packages: the delivery person delivers the goods directly to the customer, and the recipient goes to the express delivery station warehouse to find the package themselves. In these processes, there are often problems with the time connection between the delivery person and the recipient, the package is not collected for a long time, and the recipient's package is lost, resulting in low sorting efficiency and unsafe delivery. It is also common for express delivery vehicles to get lost or take detours due to unclear location of the target point; in addition, sensors are susceptible to interference, which can block information transmission. We need to improve these problems. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the express delivery smart vehicle of the present invention in conjunction with the accompanying drawings.

[0025] like Figure 1 Figure 2 Figure 3As shown, the express delivery smart car of the present invention includes a main body, a control system, a drive system, and an unlocking system. The main body is a two-layer rectangular parallelepiped structure, 15 cm long and 9 cm wide, with the first layer 3 cm high and the second layer 8 cm high. The two layers share a rectangular partition 106 in the middle. The first layer of the rectangular parallelepiped structure includes a first-layer front panel 105, a first-layer right panel 115, a first-layer left panel 119, and a first-layer rear panel 120. The second layer of the rectangular parallelepiped structure includes a second-layer front panel 107, a second-layer right front panel 116, and a second-layer left front panel 123 for the front express cabinet, and a right rear panel 117, a second-layer rear panel 121, and a second-layer left rear panel 122 for the rear equipment storage space. The express cabinet and the equipment storage space share a second-layer front and rear partition 118 in the middle, and a top panel 108 on top. The chassis 104 of the smart car is made of acrylic. The control system includes a main control board 110 of STM32f103c8t6, ​​a 12V lithium battery, and various peripherals connected to the main control board 110, including four infrared sensors 102, a camera 109 of model OV2640, and a TFT display screen 111; the main control board 110 is located above the top plate 108, and the four corners of the main control board 110 are fixed to the top layer by four screws. The display screen 111 is located at the rear end of the top plate 108 and is inserted into the main control board 110 through a pin header to realize the transmission of electrical signals, thereby displaying the display screen 111. The system displays information related to item pickup. A camera 109 is placed at the front of the top plate 108 and connected to the main control board 110 via a pin header. It scans and captures QR codes, transmitting coordinate location information to the main control board 110 for processing. A lithium battery is secured to the chassis 104 with glue, and power is supplied to the main control board 110 via wires. Four infrared sensors 102 are sequentially secured to the lower front of the chassis 104 via four copper pillars 103. The angle and spacing of the sensors are manually adjusted based on the width of the black line used, ensuring that the distance between the two middle infrared sensors is greater than the black line, facilitating black line tracking for the smart car. The drive system includes two rubber tires 101 secured to the underside of the chassis 104, auxiliary wheels 113 secured to the rear end of the chassis 104, and two DC motors 114 secured to the inside of the rubber tires 101. The DC motors 114 are connected to the lithium battery. When activated, they rotate the rubber tires 101, achieving the desired rotation effect. The unlocking system consists of a SIM900A communication module and a key module 112. The keypad module 112 is a 4x4 matrix keyboard. The communication module is connected to the main control board 110 via wires and is located in the equipment storage space at the rear of the second level of the cart. Driven by the code within the microcontroller, the communication module sends a random six-digit password to the recipient. The keypad module 112 is connected to the main control board 110 via wires and screwed to the right rear panel 117 of the second level, making it easy for the recipient to enter their password.A servo is fixed on the back of the right front panel 116 of the second layer. The servo is connected to the main control board 110 through wires to complete the association with the unlocking system. After the password is entered correctly in the unlocking system, the code in the microcontroller drives and controls the servo, causing the servo to rotate to achieve the purpose of controlling the opening and closing of the express cabinet door, making it easier for the recipient to pick up the express.

[0026] like Figure 4 As shown, the following is the workflow of the express delivery smart car of the present invention. First, preset the black lines of the grid, and select a corner of the grid on the grid as the starting point of the express delivery car. If the coordinates of the express delivery point are (1, 2), first, a QR code with coordinate information of (1, 2) is required, where the QR code is generated on the website using existing technology, and scanned by the OV2640 camera 109 on the top of the express delivery smart car. The camera transmits the read position coordinates through an electrical signal to the main control board 110 for processing, and drives the rubber wheel 101 to rotate forward through the existing code. The auxiliary wheel 113 plays the role of auxiliary sliding, and the delivery of the express delivery smart car begins. Under the recognition of the four infrared sensors 102 at the front end of the bottom plate, the car is controlled by the code, first tracking along the horizontal axis and then turning left to track the vertical axis. Upon arrival at the delivery point, the wheels stop, and the smart delivery vehicle stops. The microcontroller generates a random six-digit password using existing SMS communication code, drives the SIM900A communication module, and sends the password via SMS to the recipient. After receiving the SMS, the recipient enters the received password into the key module 112 at the right rear end of the vehicle. Once the microcontroller determines the password is correct, it runs the existing servo rotation code to activate the servo, which opens the right front panel 116 of the second-level express cabinet, allowing the recipient to complete the collection. The vehicle then rotates in place, turns around, and returns to the starting point along the grid line, completing the delivery and collection process.
