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 a heat lamp for heat preservation. 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 a heat-insulating lamp. By adding an insulation structure to the food storage compartment of the delivery vehicle, the delivered food is kept warm, preventing it from cooling down during transportation and preserving its flavor. The specific solution is as follows:

[0008] An unmanned food delivery vehicle with heat lamp insulation includes a lower driving component and an upper box; the upper box is mounted on the upper part 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 is equipped with a heating lamp on its top for heating the interior space. Mounting positions are located on the inner walls at opposite ends of the food storage box for mounting a support tray. Once installed, the support tray is parallel to the bottom of the food storage box and used to hold food items. The support tray includes an upper tray and a lower tray, respectively mounted on the mounting positions, located on upper and lower layers. A ventilation groove is provided at one end of the upper tray, extending to the other end. 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, opposite to the ventilation groove, and a hot air blower is installed inside the backup compartment. An air inlet and an air outlet are provided on the box wall where the food storage box connects to the backup compartment. The air inlet is installed above the upper tray, and the air outlet is installed between the upper tray and the lower tray. The air outlet duct of the hot air blower passes through the air inlet and is connected to the food storage box.

[0012] Furthermore, a dehumidifier is also provided, which is installed inside the trunk. The air inlet pipe of the dehumidifier is connected to the air outlet, and the air outlet of the dehumidifier is connected to the air inlet pipe of the hot air blower.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Furthermore, the top of the upper housing is provided with a lifting hook for lifting and installing the upper housing.

[0018] Furthermore, the lower driving components include a chassis, transmission assembly, tire assembly, steering assembly, braking assembly, power assembly, battery, and control assembly.

[0019] In use, first install the support tray by screwing bolts through the threaded holes on the mounting strip 211 and into the threaded holes in the mounting position 23 to secure the support tray. The upper tray 21 is installed above the lower tray 22, with one side of the ventilation groove 212 facing away from one end of the rear compartment 3. Then, hot air is sent in through the hot air blower 31 to maintain the temperature inside the food storage compartment 2. The hot air enters above the upper tray 21, passes through the ventilation groove 212, and enters the space between the upper tray 21 and the lower tray 22. It then returns to the dehumidifier 32 through the air outlet for dehumidification. The dehumidified hot air returns to the hot air blower 31 for reheating and then re-enters the food storage compartment 2.

[0020] The present invention has the following advantages over the prior art:

[0021] (a) By adding an insulation structure to the food storage box of the delivery vehicle, heating lamps and hot air are used to heat the food storage box and keep the food on the tray surface warm, so as to prevent the food from cooling down during transportation and preserve the flavor of the food.

[0022] (ii) Since the temperature difference between inside and outside can easily cause water vapor to be generated inside the food storage box, affecting the constant temperature state, and reducing the service life of the food storage box and causing certain pollution, the dehumidification function is added to ensure that the inside of the food storage box is dry and to better maintain the constant temperature state.
