Detailed Description

Referring to fig. 1 to 5, the detailed structure of the present invention is described in detail, and the embodiment is shown in fig. 1 to 5, which is a folding and horizontal type intelligent seat table structure, which is installed at the rear portion of the seat back of a train, and is improved by using the existing folding type seat table structure, a folding table is installed at the rear portion of the seat back, the folding table 3 is kept in the vertical folding and horizontal unfolding state with the seat back by using the support arms 1 at both sides through the hinge mode, telescopic limit rails 11 can be installed at both sides of the folding table, so that the folding table can slide and extend back and forth along the limit rails, the rear end of the limit rails is provided with a hinge shaft 2 and a limit pin 12, the rear portion of the folding table is hinged with the upper end of the support arm 1 through the hinge shaft 2 at both sides, the folding table is also correspondingly inserted into the arc limit groove 1-1 provided at the inner side of the upper end of the, and a limit lock for keeping the folding table in a vertical folding and folding state can be arranged at the rear part of the backrest.

The folding table plate consists of an upper layer thin table plate 6 and a lower layer table plate 9, the upper layer thin table plate can be made of a thin plate material enough for placing articles and covering the lower layer table plate 9, the lower layer table plate is embedded with a flat plate type multimedia system 10 with a touch screen, the multimedia system can be a conventional flat plate type computer system, such as a commercial or household flat computer, and can be connected with a multimedia service system of a train through a network, the multimedia service system comprises an advertisement module, a financial module, a cinema module, an entertainment module, a game module, a shopping module, a tourism module and other internet modules and the like, can be used for ordering media entertainment programs, browsing information, ordering food and providing service requirements for train attendants, and the like, and can be solidified in the multimedia system. The rear edge of the upper layer thin table plate 6 is hinged with the rear edge of the lower layer table plate through the table plate hinge 4, and the upper layer thin table plate is fixed at any position through being folded upwards to form any unfolding angle between 0 and 180 degrees with the lower layer table plate by adjusting the tightness of the hinge shaft, so that the upper layer thin table plate can be stably parked at any position, and the specific angle can be adjusted according to actual requirements. The transparent waterproof layer is arranged outside the lower-layer table board, so that liquid can be prevented from splashing on the flat touch screen when a passenger has a meal and drinks water, a multimedia system is prevented from being polluted and damaged, the folding table board can be used as a common small table board when being flatly placed, and lunch boxes, water cups, magazines and the like are placed. The telescopic limit track 11 enables the folding table panel to extend forwards, the position of the folding table panel is integrally adjusted, the interference with a seat backrest is avoided, and the maximum movable range is 120 mm; the upper end of the supporting arm 1 is hinged with the rear part of the lower table plate 9 through a hinge shaft 2.

In order to supply power to the multimedia system device, as shown in fig. 5, a power supply cable 14 is arranged, a wire outlet 15 with a waterproof rubber mat is arranged at the rear part of the folding table board close to the support arm, a wire guide groove 1-2 is arranged along the length direction at the inner side of the support arm, the terminal of the support arm is connected to the framework of the front seat, the power supply cable of the multimedia system passes through the wire outlet 15 and is connected with a power supply junction box arranged in the seat back along the wire guide groove 1-2, and the power supply cable of the multimedia system is conveniently connected with a power supply. Because the supporting arm has a certain swing angle, a small section of the power cord is reserved near the seat so that the supporting arm can swing, threading holes 1-3 for the power supply cables to penetrate through are formed in the position, close to the two lower ends, of the supporting arm, and the power cord is directly led into the front seat through a hole near the position, connected with the framework, of the supporting arm. The seat is internally provided with a power supply junction box with the voltage of 220V, and the power supply voltage of a multimedia system is 12V, so that an inverter is required to be added in the middle to convert the 220V voltage on the high-speed rail junction box into the 12V voltage, and the wiring harness terminal connected by the inverter is fixed on the junction box through a screw. Due to the particularity of the application scene, the Caledonian & Addison vehicle-mounted cable can be adopted, various international standards can be met, and the technical requirements are strictly met in the aspects of electrical safety (low smoke and low toxicity) and fire resistance (normal operation can be still kept when fire occurs).

As a further improvement, a cup placing groove 5 can be arranged on the upper layer thin table plate and/or the lower layer table plate, so that cups can be placed conveniently. In order to make the upper layer thin table plate thin enough, the cup placing grooves can be arranged at the corresponding positions of the upper layer thin table plate and the lower layer table plate. A power switch 8 and a USB and earphone interface 7 can be arranged on the side edge of the lower desk plate 9 with the multimedia system, so that the operation of passengers is facilitated. At present, charging interfaces are arranged under high-speed rail seats, but due to the distance problem, recreational operation cannot be carried out during charging, so that a passenger can conveniently charge devices such as a mobile phone, a USB interface can be arranged on the side wall of a lower-layer table board, and the USB interface can be used for the passenger to charge electrical equipment; in order to avoid interfering other passengers when the intelligent multimedia device is used, a universal earphone interface can be arranged on the side wall of the lower-layer desk board close to the USB interface, so that the intelligent multimedia device is convenient for the passengers to use. As shown in fig. 4, as a further improvement, in order to prevent passengers from using the upper thin table plate to eat and drink to contaminate the lower table plate, the front part and two side edges of the upper thin table plate are provided with downward-inclined edges 13, which play a better protection role.

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