[0002] In aviation ground support operations, catering trucks are crucial equipment for delivering meals to aircraft. When a catering truck approaches the aircraft cargo hold door, a traditional lifting mechanism raises the container containing the meal, moving it to the side of the door. Workers can then remove the meal from the container and transport it into the cargo hold. However, this traditional method of raising and lowering the entire container is structurally complex, heavy, and energy-intensive. Raising and lowering the entire container not only increases equipment costs, but the excessive weight of the lifting mechanism also negatively impacts fuel economy and vehicle stability.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

A lifting platform is slidably installed on the inner side of the cargo box, located directly above the base. A transverse support is slidably installed on the inner bottom side of the base. Symmetrically arranged support rods are hinged to the transverse support. A lifting support is fixedly installed on the outer bottom wall of the lifting platform. The top ends of the support rods are hinged to the lifting support. A lead screw is rotatably installed on the inner wall of one side of the base. A threaded hole is opened on the transverse support, and the lead screw is screwed into the inner wall of the threaded hole. A drive motor is fixedly installed on the inner wall of one side of the base, and the output shaft of the drive motor is connected to the end of the lead screw.

[0006] In a preferred embodiment of this utility model, the lifting platform is used to carry food, and the lifting platform is made of high-strength lightweight alloy material.

[0007] In a preferred embodiment of this utility model, a door is installed on one side of the compartment, and anti-slip texture is provided on the top of the lifting platform.

[0008] In a preferred embodiment of this utility model, the inner wall of the opposite side of the compartment is provided with symmetrically arranged lifting grooves, and the lifting platform is fixedly connected to symmetrically arranged lifting blocks on both sides, with the lifting blocks slidably connected to the inner wall of the lifting grooves.

[0023] A lightweight lifting mechanism for an aviation catering vehicle includes a vehicle body 1, a cargo box 2 mounted on the vehicle body 1, a door installed on one side of the cargo box 2, a base 3 fixedly mounted on the inner bottom of the cargo box 2, and a lifting platform 4 slidably mounted on the inner side of the cargo box 2. The lifting platform 4 is used to carry the catering food and is made of high-strength lightweight alloy material. The top of the lifting platform 4 is provided with anti-slip texture 5. The lifting platform 4 carries the catering food, and the high-strength lightweight alloy material used to make the lifting platform 4 effectively reduces the overall weight of the lifting platform 4. The lifting platform 4 is located directly above the base 3. A transverse support 10 is slidably mounted on the inner bottom of the base 3, and symmetrically arranged support rods 1 are hinged to the transverse support 10. 1. A lifting support 12 is fixedly installed on the bottom outer wall of the lifting platform 4. The top end of the support rod 11 is hinged to the lifting support 12. A lead screw 13 is rotatably installed on the inner wall of one side of the base 3. A threaded hole is opened on the transverse support 10, and the lead screw 13 is screwed into the inner wall of the threaded hole. A drive motor 14 is fixedly installed on the inner wall of one side of the base 3. The output shaft of the drive motor 14 is connected to the end of the lead screw 13. The lifting platform 4 is raised and lowered by the transverse support 10, support rod 11, lifting support 12, lead screw 13 and drive motor 14. Compared with the traditional lifting mechanism, the structure is optimized, the overall weight of the lifting mechanism is reduced, and the energy consumption during equipment operation is reduced.

[0024] In a specific embodiment, symmetrically arranged lifting grooves 6 are provided on the inner wall of opposite sides of the compartment 2. Symmetrically arranged lifting blocks 7 are fixedly connected to both sides of the lifting platform 4, and the lifting blocks 7 are slidably connected to the inner wall of the lifting grooves 6. Symmetrically arranged guide grooves 8 are provided on one side of the inner wall of the compartment 2.

A transverse support 10 is fixedly installed on the top outer wall of the support seat 16. When meal preparation is required, the drive motor 14 is started to drive the lead screw 13. Rotation causes the lead screw 13, in conjunction with the movable groove 15 and support seat 16, to drive the transverse support 10 to move laterally. The transverse support 10, in conjunction with the lifting support 12, causes the tilt angle of the support rod 11 to change. When the tilt angle of the support rod 11 changes, it can drive the lifting support 12 to rise and fall. At this time, the lifting groove 6, lifting block 7, guide groove 8, and guide block 9, in conjunction with the lifting groove 6, lifting block 7, guide groove 8, and guide block 9, cause the lifting support 12 to drive the lifting platform 4 to rise and fall. When the lifting platform 4 is at an appropriate height, the drive motor 14 stops running, and then the meal can be taken out from the lifting platform 4 and transported to the aircraft cargo hold to complete the meal preparation operation.

[0025] The implementation principle of a lightweight lifting mechanism for an aircraft catering vehicle in this embodiment is as follows: In specific use, the catering vehicle carries the food through a lifting platform 4 made of high-strength lightweight alloy material. When catering operations are required, the drive motor 14 is started to drive the lead screw 13 to rotate. The lead screw 13, in conjunction with the movable groove 15 and the support seat 16, drives the transverse support 10 to move laterally. The transverse support 10, in conjunction with the lifting support 12, causes the tilt angle of the support rod 11 to change. When the tilt angle of the support rod 11 changes, it can drive the lifting support 12 to rise and fall. At this time, the lifting groove 6, lifting block 7, guide groove 8 and guide block 9 are provided, so that the lifting support 12 drives the lifting platform 4 to rise and fall. When the lifting platform 4 is at an appropriate height, the drive motor 14 stops running, and then the catering vehicle can be taken out from the lifting platform 4 and transported to the aircraft cargo hold to complete the catering operation.
