Description

Technical Field

[0001] This utility model relates to the field of food truck technology, specifically to an aviation food truck. Background Technology

[0002] With the rapid development of the air transport industry, the demand for airport ground handling equipment is constantly increasing. Among them, aviation catering trucks, as key equipment specifically designed to provide food and beverages to aircraft, directly affect service quality and efficiency in terms of performance and functionality.

[0003] Traditional airline catering carts can only be adjusted vertically. When the cart is fixed, the angle of the food boxes cannot be adjusted, which is not flexible and is very limiting. Furthermore, the food boxes cannot be slid forward or backward, so there will be a gap between the aircraft and the food boxes, making it impossible to push the food boxes into the aircraft and posing a safety hazard during handling. Utility Model Content

[0006] A drive box is installed at the upper rear of the vehicle body. A first drive motor is installed inside the drive box. A lifting chamber is installed on the upper end of the first drive motor via a motor shaft. A second drive motor is installed on the upper end of the lifting chamber. The motor shaft of the second drive motor passes through the lifting chamber and is equipped with a ball screw. A screw slide is installed on the ball screw. The front end of the screw slide passes through the lifting chamber and is equipped with a curved rod. A fixed seat is installed at the front end of the curved rod. The lower end of the fixed seat is fixedly connected to the upper end of the support plate.

[0007] As a further improvement of this utility model: the upper end of the support plate is provided with two sliding grooves, and a food box is slidably installed on the upper end of the sliding grooves. A second electric hydraulic cylinder is installed in the middle of the front end of the fixed seat. The front end of the second electric hydraulic cylinder is fixedly connected to the food box. By activating the second electric hydraulic cylinder, the food box is moved into the aircraft, avoiding the gap between the aircraft and the food box and avoiding safety hazards.

[0008] As a further improvement of this utility model: the front wall of the food box is hinged with two second movable doors, and the upper rear part of the food box is hinged with a first movable door. By opening the first and second movable doors, it is convenient to take out the food in the food box, which brings convenience.

[0009] As a further improvement of this utility model: a support frame is installed at the front of the upper part of the vehicle body, and the support plate is moved onto the support frame to achieve support.

[0010] As a further improvement of this utility model: two first electric hydraulic cylinders are installed on both sides of the vehicle body, and suction cups are installed at the lower end of each first electric hydraulic cylinder. When the four first electric hydraulic cylinders are activated, the four suction cups move downward to perform adsorption, thereby improving the stability of the vehicle body.

[0011] As a further improvement of this utility model: a control panel is installed on the lower part of the left side wall of the support frame. The control panel is electrically connected to the first drive motor, the second drive motor, the first electric hydraulic cylinder, and the second electric hydraulic cylinder, which facilitates operation control.

[0012] As a further improvement of this utility model, a protective railing is installed on the upper exterior of the vehicle body, which protects the exterior of the vehicle body and improves safety.
