[0023] Embodiment 1, by Figure 1-5 The utility model relates to a foldable and storable airline dining car, comprising a car body 1, on which a dining rack assembly is fixedly mounted, the dining rack assembly comprising a plurality of longitudinally arranged placement plates 2, folding components 3 are mounted at the four corners between two adjacent placement plates 2, and a controller is mounted on the car body 1.

[0024] The folding assembly 3 includes two upper and lower rotating seats 301, the two rotating seats 301 are respectively fixedly installed on the side of two adjacent placement plates 2 close to each other, two support members 302 are installed between the two rotating seats 301, and a connecting member 303 is installed between the two supporting members 302. The rotating seat 301 includes two side plates, and a connecting shaft is fixedly installed between the two side plates. The supporting member 302 includes a supporting plate 3021, and rotating grooves 3022 are symmetrically opened at both ends of the supporting plate 3021, one of the rotating grooves 3022 is rotatably installed on the connecting shaft of the rotating seat 301, and end blocks are installed on the side of the two supporting plates 3021 close to each other. 3023, a slot 3024 is provided on the end block 3023, the connector 303 includes two connecting plates 3031, the two connecting plates 3031 are symmetrically arranged on both sides of the support plate 3021, a fixed shaft 3032 is symmetrically installed between the two connecting plates 3031, the rotating grooves 3022 at one end of the two support plates 3021 are rotatably installed on the two fixed shafts 3032, a fixed box 3033 is fixedly installed on the front of one of the connecting plates 3031, a movable plate 3034 is movably installed inside the fixed box 3033, and a movable plate 3034 is symmetrically installed on one side of the movable plate 3034 close to the connecting plate 3031 The two clamping rods 3035 are respectively clamped into the inside of the clamping grooves 3024 on the two end blocks 3023. A spring 3036 is symmetrically installed on the side of the movable plate 3034 away from the clamping rod 3035. One end of the spring 3036 is fixedly connected to the inner wall of the fixed box 3033 away from the connecting plate 3031. A magnetic block 3037 is fixedly installed on the movable plate 3034. An electromagnet 3038 is fixedly installed on one end of the fixed box 3033 away from the fixed shaft 3032. The electromagnets 3038 on the same layer are arranged in series, and the electromagnets 3038 on each layer are controlled by a controller. The electromagnets 3038 are powered off. The latching rod 3035 moves back under the elastic force of the spring 3036, so that the latching rod 3035 is disengaged from the latching slot 3024, and the upper placement plate 2 is pressed downward, so that the support plate 3021 rotates, and the two adjacent placement plates 2 are folded close to each other for easy storage. The upper placement plate 2 is pulled upward to the extreme position, and the two support plates 3021 and the connecting plate 3031 are pulled to a vertical state.

[0025] Working principle: When working, the two clamping rods 3035 on the movable plate 3034 are respectively clamped in the clamping grooves 3024 on the end blocks 3023 of the two support plates 3021 close to each other, so that the two support plates 3021 and the connecting plate 3031 remain vertical, thereby supporting the placement plate 2, so that the placement plate 2 can be used to place items;

[0026] When the dining rack assembly needs to be folded, the controller controls the electromagnet 3038 to be powered off, so that the repulsive force of the electromagnet 3038 on the magnetic block 3037 disappears. At this time, the latch rod 3035 moves back under the elastic force of the spring 3036, so that the latch rod 3035 is disengaged from the latch slot 3024, and then the upper placement plate 2 is pressed downward, so that the support plate 3021 rotates, so that the two adjacent placement plates 2 are folded close to each other for easy storage;

[0027] When it is needed, the upper placement plate 2 is pulled upward to the extreme position, and the two support plates 3021 and the connecting plate 3031 are pulled to a vertical state. The controller controls the electromagnet 3038 to be energized to generate a repulsive force on the magnetic block 3037, so that the locking rod 3035 moves outward and is locked into the slot 3024, making it convenient for the dining rack assembly to be opened and used.
