Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, and in particular to an unmanned delivery vehicle. Background Art

[0002] Antennas and LiDAR are crucial components in the current development of autonomous delivery vehicle technology. LiDAR plays a key role in detecting surrounding environmental information during operation, such as detecting obstacles and identifying road boundaries, providing a basis for vehicle navigation and obstacle avoidance. Antennas are responsible for receiving and transmitting signals, ensuring proper communication between the vehicle and control centers.

[0003] Currently, LiDAR sensors are typically exposed on the exterior of unmanned delivery vehicles. In actual operating scenarios, such as narrow streets and crowded delivery points, vehicles are prone to collisions with surrounding objects. Because LiDAR sensors lack effective protective measures, this exposed installation method makes them extremely vulnerable to damage in the event of a collision. Once LiDAR sensors are damaged, the vehicle's environmental perception capabilities will be severely impacted, potentially preventing accurate mapping, positioning and navigation, and obstacle detection. This can lead to safety incidents and affect the normal execution of delivery missions. Furthermore, LiDAR sensors are relatively expensive. Utility Model Content

[0023] The present invention will be further described with reference to the following embodiments.

[0024] Depend on Figures 1 to 4 As can be seen, the unmanned delivery vehicle described in this embodiment includes a housing 1; a placement cavity 11 is provided in the housing 1; a controller 21 and a wireless module 22 are provided in the placement cavity 11; one end of the housing 1 is recessed inward to form a strip groove 3; a first antenna 41 and a second antenna 42 are rotatably provided in the strip groove 3; the first antenna 41 and the second antenna 42 respectively protrude into the placement cavity 11 and are electrically connected to the wireless module 22; a laser radar 51 is provided in the strip groove 3; the laser radar 51 and the wireless module 22 are respectively electrically connected to the controller 21;

[0025] The first antenna 41 and the second antenna 42 are respectively arranged on both sides of the laser radar 51 ; the sum of the length of the first antenna 41 , the length of the second antenna 42 and the length of the laser radar 51 is less than the length of the strip slot 3 .

[0026] Specifically, the unmanned delivery vehicle described in this embodiment can store the first antenna 41 and the second antenna 42 into the strip slot 3 when idle, thereby reducing the overall space occupied by the unmanned delivery vehicle. When needed, it is only necessary to rotate the first antenna 41 and the second antenna 42 so that the first antenna 41 and the second antenna 42 extend out of the strip slot 3 to facilitate the transmission of wireless signals. In addition, this embodiment prevents the laser radar 51 from being directly exposed to the surface of the shell 1 by arranging the laser radar 51 in the strip slot 3, thereby preventing the laser radar 51 from being damaged when the unmanned delivery vehicle collides, and effectively protecting the laser radar 51. In addition, the sum of the length of the first antenna 41, the length of the second antenna 42 and the length of the laser radar 51 is less than the length of the strip slot 3, so that the first antenna 41, the second antenna 42 and the laser radar 51 can be effectively stored when idle.

[0027] In the unmanned delivery vehicle described in this embodiment, the first antenna 41 and the second antenna 42 are rotatably mounted on the top of the strip slot 3, while the laser radar 51 is mounted on the bottom of the strip slot 3. This arrangement allows the first antenna 41 and the second antenna 42 to be staggered as much as possible from the laser radar 51, preventing mutual interference and making the overall structure more stable and reliable.

[0028] In the unmanned delivery vehicle described in this embodiment, a first stopper 43 is provided at the top of the strip-shaped slot 3 to limit the rotation angle of the first antenna 41; a second stopper 44 is provided at the top of the strip-shaped slot 3 to limit the rotation angle of the second antenna 42. These arrangements prevent the first antenna 41 and the second antenna 42 from excessively rotating and colliding with the laser radar 51.

[0029] In the unmanned delivery vehicle described in this embodiment, an anti-collision strip 12 is provided on the outer periphery of the bottom of the housing 1. The above arrangement can protect the unmanned delivery vehicle as a whole.

[0030] In the unmanned delivery vehicle described in this embodiment, the bottom of the housing 1 is provided with a first drive wheel 61, a second drive wheel 62, and a universal wheel 63; the universal wheel 63 is disposed between the first drive wheel 61 and the second drive wheel 62; the first drive wheel 61 and the second drive wheel 62 are each electrically connected to the controller 21. This arrangement enables the unmanned delivery vehicle to move in a straight line or make a turn by controlling the rotational speeds of the first drive wheel 61 and the second drive wheel 62 in conjunction with the universal wheel 63.

[0031] In the unmanned delivery vehicle described in this embodiment, an ultrasonic radar 52 is provided at the other end of the housing 1. Through the above arrangement, the laser radar 51 and the ultrasonic radar 52 cooperate to continuously monitor obstacles and potential safety hazards along the way.

[0032] In the unmanned delivery vehicle described in this embodiment, one end of the housing 1 is provided with a power knob 71, an emergency stop button 72, a reset button 73, and a start / stop button 74; the power knob 71, emergency stop button 72, reset button 73, and start / stop button 74 are each electrically connected to the controller 21. In the unmanned delivery vehicle described in this embodiment, the other end of the housing 1 is provided with a power meter 81, a USB debugging port 82, and a LAN network port 83; the power meter 81, USB debugging port 82, and LAN network port 83 are each electrically connected to the controller 21. In the unmanned delivery vehicle described in this embodiment, the four corners of the housing 1 are provided with a first signal light 91, a second signal light 92, a third signal light 93, and a fourth signal light 94; the first signal light 91, the second signal light 92, the third signal light 93, and the fourth signal light 94 are each electrically connected to the controller 21. This configuration can achieve various reminder effects. In the unmanned delivery vehicle described in this embodiment, a battery pack 23, a charging interface 24, a power module 26 and a wiring module 25 are provided in the placement cavity 11; the battery pack 23, the charging interface 24, the power module 26 and the wiring module 25 are electrically connected to the controller 21 respectively.

[0033] The unmanned delivery vehicle's operational process is coordinated and controlled by a series of carefully designed modules. When the controller 21 receives a delivery task instruction from the upper system, the unmanned delivery vehicle's delivery process is initiated. The controller 21 transmits these task instructions to the peripheral centralized control board, which converts them into specific operational signals, activating the travel motor and reducer in the drive unit, driving the first and second drive wheels 61 and 62, and guiding the unmanned delivery vehicle along a dynamically planned or preset path to the destination.

[0034] While driving, the unmanned delivery vehicle relies on its onboard safety sensors, such as the LiDAR 51 and ultrasonic radar 52, to continuously monitor obstacles and potential safety hazards along the way. These sensors work in conjunction with the safety protection system's anti-collision strips 12, voice module, signal lights, and other equipment to ensure safe driving. If an obstacle is detected, the unmanned delivery vehicle automatically stops or takes a detour to ensure safe driving. If there are no obstacles along the way, the unmanned delivery vehicle will continue along the predetermined route.

[0035] The peripheral centralized control board precisely controls the operation of various actuator motors based on the station or coordinate information in the mission instructions and performs real-time status monitoring. The operation panel features common function keys such as the power knob 71, emergency stop button 72, reset button 73, and start / stop button 74, facilitating quick operation and control. It also supports remote control and programming to meet the needs of diverse users.

[0036] The vehicle's power supply module utilizes a high-performance battery pack 23 and a voltage regulator module, providing a stable power supply and extending battery life. It is also equipped with a charging port and a battery indicator 81, allowing users to easily monitor battery status and perform charging operations. The status display uses a three-color signal light and a buzzer to intuitively display the vehicle's operating status and fault information. If an abnormality occurs, the status display will promptly issue an alarm and prompt the user to take corrective action.

[0037] The IO expansion module provides a rich set of resources, including digital IO interfaces, CAN communication interfaces, UART interfaces, various power supply levels, and LAN interfaces, allowing users to easily expand functions and integrate systems according to their actual needs. Through the IO expansion module, users can seamlessly connect and collaborate with other devices or systems.

[0038] The wireless module 22 enables real-time communication with the host computer and dispatch system. It primarily utilizes industrial Wi-Fi modules and dual-band antennas to achieve high-speed, stable wireless communication. This allows users to remotely control and monitor the vehicle's operating status and location, improving reliability and safety, especially in multi-vehicle projects.

[0039] Throughout the delivery process, the peripheral centralized control board works efficiently with the controller 21, wireless module 22, and other peripheral components, making intelligent decisions to ensure the unmanned delivery vehicle successfully completes its delivery mission. This highly effective control mechanism enables the unmanned delivery vehicle to achieve efficient, safe, and accurate material handling and delivery in complex and changing working environments. This control mechanism enables the unmanned delivery vehicle to demonstrate excellent performance, enabling it to flexibly execute tasks in both confined spaces and changing environments, ensuring high efficiency, reliability, and cost-effectiveness in logistics and delivery.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
