[0012] The present invention will be further clarified below with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent forms of modification of the present invention by those skilled in the art all fall within the scope defined by the appended claims of this application.

[0013] like Figure 1 and 2 As shown, the dual-screen flight electronic kneeboard of the present invention comprises a card fixing seat, a task card bag for storing task cards, and a tablet fixing seat for fixing a tablet, wherein: The rear end of the tablet fixing seat is hinged to the rear end of the card fixing seat, so that the tablet fixing seat can be turned over and overlapped with the card fixing seat; The top of the card fixing seat is provided with a card fixing clamp spring, a positioning seat and a tablet fixing seat lock buckle, and the tablet fixing seat lock buckle is hinged with the positioning seat. When the tablet fixing seat is turned over and overlapped with the card fixing seat, the tablet fixing seat lock buckle can be turned over and buckled on the tablet fixing seat; A limit spring positioning bead is also provided on the inner side of the positioning seat, and a groove adapted to the limit spring positioning bead is also provided on the top of the tablet fixing seat. When the tablet fixing seat and the card fixing seat are overlapped, the limit spring positioning bead can be embedded in the groove to fix the tablet fixing seat; The card fixing spring is a U-shaped spring, and the task card bag is provided with a fixing hole matched with the fixing spring. The task card bag is passed through the fixing hole on the fixing spring and can be turned up and down around the fixing spring.

[0014] Preferably, a spring piece capable of tightly clinging to the tablet is further provided at the center of the top end of the tablet fixing seat; and a paddle is provided at the top end of the tablet fixing seat relative to the tablet fixing seat lock.

[0015] As a preferred embodiment, it also includes a strap fixing plate arranged on the back of the card fixing seat, and a quick-insert elastic strap arranged on the strap fixing plate, wherein the quick-insert elastic strap includes an elastic band, and quick-insert buckles and buckle connectors arranged at both ends of the elastic band. Specifically, the quick-insert elastic strap is used to fix the entire set of flight electronic kneeboard on the pilot's thigh. The present invention is designed to use a retractable elastic band, a quick-insert buckle and an open connector. The elastic band allows the entire fixing strap to have a continuous tension force, which can achieve reliable fixing of the flight electronic kneeboard while meeting the requirement of synchronous relaxation of the strap when the flight anti-gravity suit is suddenly inflated and pressurized under large overload. The quick-insert buckle is used for the pilot to quickly fix the entire set of flight electronic kneeboard, and the open connector is used for the quick disassembly and assembly of the strap and the strap interface of the card fixing seat, so as to achieve the ultimate portability of the entire set of flight electronic kneeboard after the strap is removed. Furthermore, a quick-insert safety belt is also provided on the strap fixing plate, which is used to limit the entire set of products under large inertia when the aircraft lands.

[0016] Preferably, the flat panel is a dual-screen flat panel, including an active transmissive screen and a passive reflective screen. The designed dual-screen flat panel realizes the electronic processing of data, solves the storage and rapid retrieval of a large amount of complex data. The two screens respectively adopt an active transmissive screen and a passive reflective screen. The active transmissive screen enables use under low-light conditions for night navigation, and the passive reflective screen solves the problem that the traditional display screen cannot be read under strong sunlight on the cloud. The embedded task module is inserted and embedded into the dual-screen flat panel, and different task modules can be used to respectively realize different functions such as satellite navigation and positioning, satellite communication, and image data transmission.

[0017] The operation method of the product of the present invention: Put the user's paper task card into the transparent card bag, unlock the U-shaped card fixing spring on the card mounting seat, install the card bag onto the card fixing spring through two fixing holes and close and lock it; Insert and embed the embedded task module into the dual-screen flat panel, unlock the flat panel fixing seat lock and lift the flat panel fixing seat, fix the dual-screen flat panel on the flat panel fixing seat through the elastic limit card slot with the selected display screen facing outward, lower the flat panel fixing seat and lock the flat panel fixing seat lock to form an integral connection with the card fixing seat; Insert the open connectors of the two quick-insert elastic straps into the strap interfaces on the back of the flat panel fixing seat and close and lock them, adjust the elastic straps to an appropriate length and fasten them to the user's thigh through the quick-insert buckles; Put one end of the quick-insert safety belt onto the user's waistband, and insert the end with the quick-insert buckle into the safety belt interface on the back of the card fixing seat; When it is necessary to switch between using the paper task card and the electronic card on the dual-screen flat panel, first unlock the two flat panel fixing seat locks, lift the flat panel fixing seat, turn the card bag outwards through the U-shaped spring, and then reset and fix the flat panel fixing seat onto the card mounting seat. At this time, the traditional task card can be used compatibly. Therefore, the present invention solves the problems that data cannot be quickly retrieved and real-time rapid task planning cannot be carried out in the traditional way, and also solves the problem that the liquid crystal screen of the instrument cannot be clearly seen under strong sunlight on the cloud. With different task modules, it can solve the problem of diversified task implementation.

[0018] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and technical concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
