Background

The flight recorder, commonly called as a black box, is used for evidence finding and analysis after an accident, and the throwing type recorder is produced by taking the flight recorder out of the sea aiming at the problem of difficult salvage of the flight recorder.

When the airplane crashes, the throwing recorder receives the ejection signal and actively ejects and separates from the airplane body, so that the airplane is prevented from suffering from a severe crash environment in the crash process of the airplane, and the survival probability of the recorder after the airplane crashes is improved. According to the characteristic of active ejection and separation, the recorder is called a throwing recorder. The throwing recorder is a reliable backup of the fixed protective recorder, can float on the sea surface and transmits a radio rescue signal.

In the throwing and separating device of the present invention, the driving means 10 preferably comprises a servo motor, which is arranged to rotate in a selected direction. It should be understood that the drive means 10 need not necessarily be a servo motor, but may include other electromagnetic means, mechanical means, pneumatic means, hydraulic means, etc. In the preferred embodiment, the selected direction is the first rotational direction R shown in FIG. 2, i.e., counterclockwise. In addition, the selected direction can be designed to be clockwise according to requirements. The drive device 10 may be in electrical communication with a controller of the aircraft to perform a predetermined angular rotation in a selected direction upon receiving the discharge signal. The transmission mechanism 20 is able to transform the rotary power in the first direction of rotation R from the driving device 10 into the translational power in the second direction Y for the abutment 30 through mechanical communication.

In the throwing separation device of the present invention, the transmission mechanism 20 is preferably provided in pairs, thereby sufficiently converting the rotational kinetic energy of the driving device 10 and offsetting the lateral force of deflection, so that the throwing separation device 100 is stable. It should be understood that the transmission mechanism can be arranged only on one side according to the requirement, so that the whole volume is reduced, and the transmission mechanism is convenient to place in a small containing space. The paired arrangements of the transmission 20 are not completely mirror images and, in the following description, specific reference will be made to the same and different arrangements.

Fig. 2 is a front view of the preferred embodiment jettisoning separator device 100. As can be seen in FIG. 2, the mechanical communication of the preferred embodiment drive mechanism 20 includes sliding components and a linkage structure. The sliding member can provide a translational movement in a first direction X in a sliding manner (wherein the first direction X is perpendicular to the second direction Y), preferably comprising a slider 24, 24 'slidable in the first direction X and a sliding guide 23 for guiding and limiting the movement state of the slider 24, 24'. In particular, the sliding guides 23 are preferably sliding tracks and the slides 24, 24' are preferably corresponding sliders. The two sliding blocks are arranged on the same straight line with the sliding track and the motor at equal intervals in the horizontal direction, and the sliding blocks are limited by the sliding track to do single-degree-of-freedom reciprocating motion in the first direction X, namely, the sliding blocks are translated along the positive direction and the negative direction of the first direction X. And the sliders and the slide rails have corresponding edges (not shown) and grooves (not shown) to prevent separation from the slide rails. Both ends of the slide rail have a restricting portion (not shown) to restrict the slider from being excessively displaced beyond the slide rail.

As seen in fig. 2, the coupling structure of the transmission mechanism 20 includes a pulling part coupling the sliding part and the driving device 10 and transmitting power, and a pushing part coupling the sliding part and the abutting part 30 and transmitting power. The pulling means of the preferred embodiment comprises linkages 21, 21 ', which linkages 21, 21' are fixedly attached to the outer circumference of the driving device 10 by means of mechanical fastening (fasteners, form fit, etc.) to rotate together with the driving device 10, i.e. simultaneously in the same direction and angle. Furthermore, the traction means of the preferred embodiment also comprise traction members 22, 22 ' connecting the corresponding linkage members 21, 21 ' and the corresponding slide members 24, 24 '. In particular, the linkages 21, 21' are preferably linkage bars fixed to the motor and extending opposite each other in the second direction Y (i.e. the two linkage bars extend in the positive and negative directions of the second direction Y, respectively). The pulling members 22, 22' are preferably pulling rods, each of which has one end pivotally coupled to a corresponding linkage rod by a rotatably connected structure such as a pivot, and the other end pivotally coupled to a corresponding slider by a revolute pair (not shown). In a preferred embodiment, the two linkage bars are of equal length and the two puller bars are of equal length to balance the forces. When the motor rotates, the two sliding blocks respectively do translational motion in the first direction X through the movement of the corresponding traction parts (the traction rods and the linkage rods), so that the rotary power from the motor is converted into the translational power along the second direction Y.

It should be understood that the form of the pulling member is not limited to the linkage rod and the pulling rod, but may take any suitable configuration for transmitting power; for example, the linkage is not limited to two separate rods, but may be a one-piece long rod with an intermediate fixing portion, or a disc, block, or cylindrical linkage member having a predetermined outer profile shape; and the pulling member may be a strap-like, cam-like pulling member, for example.

As can be seen in fig. 2, the pushing member of the preferred embodiment comprises pushers 25, 25'. The pushing member 25, 25' has one end pivotally coupled to the sliding part and the other end pivotally coupled to the abutting member 30. In particular, the pushing members 25, 25' are preferably pushing rods, each of which has one end pivotally coupled to the corresponding slider by a revolute pair and the other end pivotally coupled to the abutting member 30 by a revolute pair. In a preferred embodiment, the two push rods are of equal length to balance the forces. Therefore, in the preferred embodiment of the present invention, when the two sliding blocks perform the translational motion due to the rotation of the motor, the abutting member 30 is driven by the translational motion of the two sliding blocks, so as to translate along the second direction Y, thereby converting the translational power along the first direction X into the translational power along the second direction Y.

Specifically, the abutting member 30 is preferably an abutting seat, and the throw-type recorder is placed in a seating recess of the abutting seat to prevent the recorder from coming out of contact with the abutting seat. It will be appreciated that the form of the traction means is not limited to abutment seats but may take any suitable power transmitting configuration, such as abutment plates, abutment blocks or the like.

The throwing separation device according to a preferred embodiment of the invention shown in fig. 2 is in its initial position to throw the recorder after the signal has been received.
