Description

Technical Field

[0001] This utility model relates to the field of unmanned delivery vehicles, specifically a solar-powered automatic load-grabbing mobile vehicle. Background Technology

[0002] With the rapid development of e-commerce, online shopping has gradually become a part of people's daily lives. Statistics show that the number of online shoppers has grown exponentially in recent years, with online and offline businesses continuously expanding, driving the rapid development of the global e-commerce industry. However, with the surge in e-commerce volume, logistics and delivery, especially the "last mile" delivery problem, has become a major bottleneck in the development of the e-commerce industry. The last mile delivery problem refers to the final distance from the distribution center or warehouse to the consumer. This process typically takes place in various urban communities or rural areas. Due to factors such as geographical location, traffic conditions, and the volume of deliveries, last-mile delivery often faces numerous challenges, including high costs, low efficiency, and difficulty in efficient management.

[0003] Currently, many e-commerce companies rely on traditional courier delivery models to complete this process. While this method ensures timely delivery to consumers, it is relatively expensive, especially with rising delivery personnel and transportation costs, making logistics costs a major issue that companies must address. Furthermore, due to increasing labor costs and urban traffic congestion, courier delivery faces problems such as inefficiency, poor timeliness, and resource waste.

[0004] Limitations of courier delivery:

[0005] High costs: With the continuous rise in labor costs, the wages of couriers, as well as transportation and equipment costs, are constantly increasing, which directly leads to an increase in delivery costs.

[0006] Low efficiency: Delivery personnel need to rely on manual methods to deliver orders one by one, especially in crowded cities or remote areas, which results in low delivery efficiency, longer delivery times, and decreased customer satisfaction.

[0007] Poor sustainability: With changes in population structure and the acceleration of urbanization, the shortage of delivery personnel is becoming increasingly serious, making it difficult to meet the continuously growing e-commerce demand.

[0008] Therefore, how to reduce costs while ensuring delivery efficiency has become a core issue facing e-commerce logistics. To break through this bottleneck, more and more e-commerce companies and logistics companies are exploring new models of intelligent logistics and automated delivery. These emerging technologies include driverless vehicles, drones, automated warehousing, and intelligent delivery robots, aiming to solve the last-mile problem, improve delivery efficiency, and reduce labor costs.

[0009] However, existing automated delivery vehicles still have some design flaws. Firstly, many vehicles lack strong adaptability and cannot cope with complex terrain or environmental changes. Secondly, existing automated delivery vehicles generally can only complete basic cargo transportation tasks, but do not have the ability to automatically load, stack, sort, and pack goods. Therefore, couriers or operators still need to manually handle and arrange the goods. Especially in places with a wide variety of goods and complex stacking arrangements, manual intervention becomes a bottleneck to logistics efficiency. Utility Model Content

[0010] The purpose of this utility model is to provide a solar-powered automatic load-grabbing mobile vehicle with multiple functions such as automatic grabbing, loading, stacking and transportation. It can efficiently complete multiple links from warehousing to distribution and shorten the cargo handling time through automated operation.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a solar-powered automatic load-grabbing mobile trolley, comprising a frame, a powered adaptive wheel set disposed on the bottom side of the frame, and a carriage disposed on the frame. The adaptive wheel set can automatically adjust according to different ground conditions, providing stable driving performance and ensuring that the trolley can move smoothly and overcome complex terrain. A headlight and a functional module for road condition detection, positioning, and obstacle avoidance are provided on the front side of the carriage. A bracket is provided on the top side of the carriage, and an automatically opening double-leaf door is provided on one side of the carriage. A gripping component for grabbing goods is provided inside the carriage. The gripping component includes a lifting module, a support platform, a short-distance moving module, and a gripping manipulator. The lifting module is a scissor-type lifting frame, and a support platform is installed on the front side of the lifting module.

[0012] Preferably, a short-distance moving module is installed on the support platform. The short-distance moving module includes a guide rail, a chain, a transmission wheel, a power wheel, a drive device, and a support platform. The rear end of the guide rail is vertically connected to the support platform, and the front and rear sides of the guide rail are connected to the support platform through auxiliary brackets. The support platform slides on the guide rail.

[0013] Preferably, the transmission wheel and the power wheel are distributed at the front and rear ends of the guide rail. The power wheel is driven by a drive device, and the transmission wheel and the power wheel are linked by a chain. The support platform is connected to the chain, and the support platform moves along the length of the guide rail when the power wheel links with the transmission wheel.

[0014] Preferably, the support platform includes a support plate and auxiliary legs installed at the four corners of the bottom of the support plate. The auxiliary legs include a column, an electric push rod and a pad arranged from top to bottom.

[0015] Preferably, a gripping robot is installed on the support plate. The gripping robot is a four-axis robot, and its end effector is also equipped with a barcode reader for barcode recognition or a CCD reader for cargo recognition. The gripping assembly assists the mobile trolley in loading and stacking operations. When the gripping assembly is working, the lifting module unfolds, allowing the support platform, short-distance movement module, and gripping robot to move out of the carriage. The gripping robot can move a short distance along the guide rail using the short-distance movement module. When it moves to a suitable position (a workstation convenient for loading, stacking, and unloading), it extends vertically downward using an electric push rod and supports itself on the ground to keep the support plate stable. The gripping robot on the support plate identifies the cargo and grabs it to the designated position in the carriage.

[0016] Preferably, the gripping component design enables the cart to perform tasks such as loading, stacking, and unloading at multiple workstations, reducing manual operation and improving efficiency. Through automatic identification and precise gripping, it can significantly shorten material handling and cargo stacking time, adapt to different types of warehousing and logistics environments, improve overall operational efficiency, and ensure flexible handling of cargo gripping and processing tasks in various operating environments.

[0017] Preferably, a photovoltaic power supply module is installed on the bracket. The photovoltaic power supply module includes a photovoltaic panel and a photovoltaic inverter. The output terminal of the photovoltaic power supply module is connected to a power source on the bottom of the vehicle body. By providing power through solar energy (photovoltaics), dependence on external power sources is reduced, the working duration of the vehicle is increased, and certain environmental advantages are provided.

[0018] Preferably, the functional module includes a lidar, an obstacle avoidance camera, and a BeiDou locator. This functional module can accurately perceive the surrounding environment and perform real-time positioning, ensuring the vehicle's autonomous navigation and obstacle avoidance capabilities in complex environments.

[0019] Preferably, a scanner for barcode reading or facial recognition is installed outside the vehicle compartment. The scanner is a camera based on facial or QR code recognition. The scanner can realize user identification based on facial recognition or QR code, which facilitates automatic identification and delivery of goods and improves the intelligence and ease of operation of the mobile cart.

[0020] Compared with the prior art, the beneficial effects of this utility model are:
