The sequence numbers in the figures illustrate: the water cup comprises a supporting arm 1, a folding table panel 2, a screen panel 2-1, a projection supporting plate 2-2, a limiting slide rail 3, a slide rail shaft 3-1, a limiting pin 3-2, an arc-shaped limiting groove 4, a water cup placing groove 5, a projector 6 and a groove 7.

Detailed Description

The specific structure of the utility model is explained in detail according to fig. 1 and 5, as shown in fig. 1 and 2, a novel seat table structure with a projection screen, the chair table plate structure is arranged behind a chair backrest plate, the external dimension of the folding table panel 2 can adopt a plate type light material structure with the length of 396 mm, the width of 240 and the height of 21mm, the whole chair folding table form is adopted, the folding table panel 2 is hinged with a supporting arm 1 through limiting slide rails 3 on two sides, the supporting arm and the limiting slide rails adopt a conventional connecting mode, the root part of the supporting arm is connected and hinged with a front row chair framework, the inner side of the upper end of the supporting arm is provided with an arc limiting groove, the rear end of the limiting slide rail 3 is provided with a slide rail shaft 3-1 or a, and the limit pin 3-2 of the limit slide rail is arranged in the arc-shaped limit groove 4, so that the folding table panel 2 can be fixed in a supporting state and a folding and retracting state. The technical points are as follows: the folding table panel adopts a double-layer structure with an upper layer turnover type screen plate 2-1 and a lower layer projection support plate 2-2, the projection support plate is provided with a projector 6 for projecting towards the screen plate, and the screen plate 2-1 is hinged with the inner side edge of the projection support plate 2-2. The projector adopts a micro projector, and can receive the image transmitted by the signal source in a wired or wireless mode. A power supply battery or an external power supply can be arranged in the projection support plate.

As a further improvement, as shown in fig. 4, the inner side surface of the screen plate may be set as a projection screen surface corresponding to the projector, so as to achieve a better image effect. Can set up in projection backup pad lower part through turning over the board, turn over the board and set up the position of keeping away from inboard side in projection backup pad axis through the pivot, the projector orientation is downwards when not using the projector, and the upset turns over the board and makes the projector orientation screen board during the use. A water cup placing groove 5 can be arranged on the projection supporting plate close to the edge, so that articles such as water cups and the like can be conveniently placed when the projection program is watched; the limiting slide rails can be arranged on two side edges of the lower layer of the projection support plate, and limiting slots are arranged on two sides of the projection support plate, so that the projection support plate is convenient to support and use; the edge of the projection support plate can be provided with a groove 7 for turning over the screen plate, so that the screen plate can be conveniently turned up by hands; the limit slide rail 3 can also be provided with a telescopic slide rail, so that the folding table panel can extend forwards to avoid the backrest board of the seat and tilt backwards.

The working principle and the process are as follows: when the upper part and the lower part of the folding table board are completely combined, the function of the table board is realized, water cups, lunch boxes, magazines and the like can be prevented, after the upper layer table board is opened around the hinge shaft (the opening angle can reach 180 degrees, and corresponding position adjustment can be carried out according to the use requirements of users), the back surface of the upper layer table board is just the projection area, and the micro projector pops up and enters a standby state. In order to ensure that the screen projection angle is not influenced by the adjustment of the front row of seats, the folding table top plate can slide back and forth along the sliding limiting slide rail, and the maximum sliding range is set to be 120 mm.

Realization of three working conditions

As shown in fig. 3, when the foldable table top is folded, the foldable table top is 180 degrees flush with the supporting arm and is completely fixed on the back of the backrest of the chair, so that the angle adjustment of the backrest of the chair is not affected;

as shown in fig. 1, the folding table top is in an open state, so that the using functions of passengers such as dining, reading magazines and the like are met, the folding table top can be completely in a horizontal position, and the folding table top is not influenced by the angle adjustment of the backrest of the seat;

as shown in fig. 4, in the opened state of the projection screen, the folding table panel is fully opened, and the upper screen panel is opened, so that the projection screen faces the customer and is adjusted to a proper angle;

as shown in fig. 5, when the projection screen slides back and forth, the angle of the projection screen is affected when the backrest angle of the front row of seats is adjusted, and the position of the folding table top plate can be integrally adjusted to avoid interference with the backrest of the seat in order to ensure that the proper projection screen angle is not affected.

In conclusion, the purpose of the utility model is realized.
