Description

Technical Field

[0001] This utility model relates to the field of food transportation equipment technology, and in particular to an unmanned food delivery vehicle with heat medium insulation. Background Technology

[0002] Driverless food delivery vehicles are intelligent vehicles that use autonomous driving technology to deliver food, and are typically used in schools, communities, industrial parks, or commercial parks.

[0003] The driverless delivery vehicle uses a variety of sensors, such as lidar, cameras, millimeter-wave radar, and ultrasonic sensors, to perceive the environmental information around the vehicle in real time, providing data support for vehicle decision-making and control. Combined with satellite positioning technologies such as the Global Positioning System (GPS) and BeiDou Navigation Satellite System, along with inertial navigation systems (INS) and high-precision map matching technology, it accurately determines the vehicle's position and direction of travel on the map, ensuring that the vehicle can travel accurately along the predetermined route. With the help of an intelligent control system, it can start and stop, drive normally, turn, accelerate and decelerate, and avoid obstacles within the delivery range.

[0004] The use of driverless food delivery vehicles on campus reduces the labor costs required for manual delivery, while optimizing delivery routes and times, improving delivery efficiency, and reducing operating costs.

[0005] It can operate 24 / 7 without interruption, unaffected by fatigue or emotional factors, and can quickly and accurately deliver meals to their destinations according to preset routes, shortening delivery time. Our school has used driverless delivery vehicles to deliver meals over 200,000 times in the past two years, primarily serving students and faculty. Students can order meals via a mobile app from their dormitories or classrooms. The driverless delivery vehicles can quickly deliver meals from the cafeteria or off-campus restaurants to designated locations, making it convenient for students to eat, reducing traffic pressure on campus, and improving delivery efficiency.

[0006] However, driverless food delivery vehicles typically need to wait for a certain number of orders to be received before delivering them all at once. Currently used driverless food delivery vehicles lack insulation capabilities, and excessively long delivery times or waiting periods can easily cause food to cool down, affecting its taste and flavor, and leading to a decline in user experience. Therefore, there is an urgent need for a food delivery vehicle with insulation capabilities to ensure that food does not cool down or spoil during delivery. Summary of the Invention

[0007] To address the aforementioned problems, this utility model provides a driverless food delivery vehicle with heat-insulated storage. By adding an insulation structure to the food storage compartment of the delivery vehicle, the delivered food is kept warm, preventing it from cooling during transportation and preserving its flavor. The specific solution is as follows:

[0008] A driverless food delivery vehicle with thermal insulation includes a lower driving component and an upper body; the upper body is mounted on the upper end of the lower driving component.

[0009] The upper box includes a food storage box and a rear box; the food storage box is equipped with a support tray.

[0010] The food storage box has mounting positions on the inner walls at opposite ends for mounting a support tray. The support tray is a plate-shaped box that, after installation, is parallel to the bottom of the food storage box and is used to place food and beverages. The support tray is hollow inside, and water inlet and outlet holes are respectively opened on the upper and lower surfaces. A door is hinged to the side of the food storage box.

[0011] The backup compartment is installed on one side of the food storage box, and is equipped with a heating water tank and a water pump inside. The heating water tank is equipped with an outlet pipe and an inlet pipe. The outlet pipe is connected to the water pump and then passes through the wall of the food storage box to connect with the inlet hole. The outlet pipe passes through the wall of the food storage box to connect with the outlet hole.

[0012] Furthermore, the tray is provided with a number of parallel water-blocking strips evenly spaced inside. The water-blocking strips are fixedly connected to the upper and lower bottom surfaces and one side wall inside the tray, and two adjacent water-blocking strips are respectively connected to the side walls on different sides inside the tray. The water inlet and the water outlet are respectively located at both ends of the channel formed by the gap between the water-blocking strips. The liquid entering through the water inlet flows through the gap between the water-blocking strips to the water outlet and then flows out.

[0013] Furthermore, it also includes quick-connect hoses; quick-connect fittings are provided at the water inlet and the water outlet, and quick-connect fittings are provided at the water outlet pipe and the water inlet pipe, and the water inlet and the water outlet can be connected respectively through the quick-connect hoses.

[0014] Furthermore, the mounting positions are arranged in a longitudinal strip shape, with a total of four strips, which are installed in pairs on the inner walls of opposite ends of the food storage box; several equally spaced threaded holes are opened horizontally on the mounting positions, and mounting strips are provided downward on both ends of the support tray, with four threaded holes opened horizontally on the mounting strips corresponding to the positions of the mounting positions, so that the support tray can be installed in any of the threaded holes on the mounting positions by bolts.

[0015] Furthermore, there are two support trays; they are respectively installed in the mounting position, located on the upper and lower layers; the water outlet of the upper support tray is directly opposite the water inlet of the lower support tray.

[0016] Furthermore, the side walls and doors of the food storage box are provided with insulation layers, and the insulation layers are filled with foam insulation boards.

[0017] Furthermore, the trunk body is hinged with a side door and a trunk lid, and the side wall of the trunk body, the side door, and the trunk lid are provided with an insulation layer, which is filled with foam insulation board.

[0018] Furthermore, a support plate is provided in the middle of the side of the food storage box, and an installation position is provided on the inner wall of the support rod; the box door has four panels, which are symmetrically hinged to the support plate and installed on the side of the food storage box.

[0019] Furthermore, the top of the upper housing is provided with a lifting hook for lifting and installing the upper housing.

[0020] Furthermore, the lower driving components include a chassis, transmission assembly, tire assembly, steering assembly, braking assembly, power assembly, battery, and control assembly.

[0021] First, install the tray 21 by screwing bolts through the threaded holes on the mounting strip 214 and into the threaded holes in the mounting position 22 to secure the tray 21. Then, use quick-connect hoses 27 to connect the inlet 211 to the outlet pipe 33 and the outlet 212 to the inlet pipe 34. Add water or other liquid media to the heating tank 31. After starting the heating tank 31, the liquid in the heating tank 31 is pumped into the tray 21 by the water pump 32, keeping the inside of the tray 21 heated and thus keeping the food placed on the tray 21 warm. The serpentine water-blocking strips 213 inside the tray 21 allow the liquid inside the tray to flow from the inlet 211 to the outlet 212 along the gaps, ensuring overall circulation and uniform heating. The tray 21 can be adjusted in height and can be installed in one or more layers as needed.

[0022] The present invention has the following advantages over the prior art:

[0023] (a) By adding an insulation structure to the food storage box of the delivery vehicle, the medium is heated by a heating water tank and then transported to the pallet, so that the entire pallet has a certain temperature, and the food placed on its surface is kept warm, so as to avoid the food cooling during transportation and preserve the flavor of the food.

[0024] (ii) Water-blocking strips are arranged in a serpentine pattern inside the pallet to ensure that the liquid medium is filled in and out evenly, so that the temperature of the entire pallet is uniform and it is convenient to control the temperature of the food being transported.
