Description

Overturn keyboard of airborne display Technical Field The utility model belongs to the technical field of computer equipment, and particularly relates to a turnover keyboard of an airborne display. Background The backup flight display is a critical safety device on board the aircraft for providing a backup display function in the event of a failure of the primary flight display. The backup flight display comprises a multifunctional keyboard, and mainly provides backup display and parameter setting functions for pilots when the large-screen touch display fails. The backup flight display can display pictures of a horizon instrument, a compass, an electromechanical device, parameter setting and the like in a switchable mode through peripheral keys, and parameters such as radio communication, navigation and the like can be set through the multifunctional keyboard. The existing backup flight display has two structures, namely a first independent multifunctional keyboard. In the scheme, the multifunctional keyboard and the display are separately designed, and then signal connection is realized through the opposite insertion of cables with connectors at two ends. The disadvantage is that the keyboard tray structure is designed separately or integrated on the keyboard structure, and in addition, a cable with connector plugs at both ends is required, which greatly increases the cost. Second, an integrated multi-function keyboard. In this structure, the multifunction key pad is integrated on the display panel and shares a structural housing with the display panel. Therefore, the overall size of the display is greatly increased due to the fact that the multifunctional keyboard is inherited, and the occupied area of the instrument panel is large. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the turnover keyboard of the airborne display, which is convenient to operate, simple in structure and small in occupied space. The technical scheme includes that the overturning keyboard of the airborne display comprises the display and a keyboard, the display and the keyboard are electrically connected through cables, a first groove and a second groove which are separated by a certain distance are formed in the lower end of a panel of the display, a first protruding block and a second protruding block are arranged on one side of the keyboard, the first protruding block is inserted into the first groove, the second protruding block is inserted into the second groove, the first protruding block is connected with the wall of the first groove through a rotating shaft, the second protruding block is connected with one side wall of the second groove through a clamping connecting piece, the clamping connecting piece comprises a limiting clamping block, a telescopic clamping shaft and a reset spring, the limiting clamping block is arranged on the second protruding block, two crossed straight grooves with the same width are formed in one end face of the limiting clamping block, the telescopic clamping shaft and the reset spring are sequentially arranged in a mounting hole on one side wall of the second groove, a yielding groove is formed in the mounting hole wall, one end of the telescopic clamping shaft, which is close to the limiting clamping block, a plug matched with the straight groove is arranged on the side of the telescopic clamping shaft, a deflector rod is arranged outside the yielding groove, the extending out of the first groove, the telescopic clamping shaft is inserted into the limiting clamping block, the other straight groove is arranged in the limiting clamping block, and the other plug is in the limiting clamping block, and the other straight groove is in the state of the limiting clamping block, and the other straight groove is in the extending state. As a preferable technical scheme, the rotating shaft is a damping rotating shaft. As a preferable technical scheme, a mounting surface is processed on the side surface of one end of the limiting clamping block far away from the telescopic clamping shaft, and the included angle between the mounting surface and the central line of a straight groove is 0 DEG and the included angle between the mounting surface and the central line of another straight groove is 50 deg. As a preferable technical scheme, a wire through hole is formed at the joint of the other side wall of the second groove and the second bump, and the cable passes through the wire through hole. As a preferable technical scheme, a cable protection sleeve is arranged in the wire through hole. The beneficial effects of the utility model are as follows: According to the utility model, through the design of the clamping connecting piece, the stability of the position of the keyboard in the use process is ensured, the keyboard is prevented from loosening or falling off due to accidental collision, the unfolding and the folding of the keyboard can be realized rap
