The invention relates to a claw separation and unlocking mechanism based on the principle of differential speed, which belongs to the technical field of aviation and spaceflight. The invention solves the problem that the existing unlocking and separating mechanism for aviation or spaceflight completely fails when a failure occurs, resulting in the problem that the claw cannot be unlocked. The upper part of the second claw and the upper part of the first claw are hinged at point C through a rotating shaft, and the upper part of the second claw and the lower part of the first claw are pinned at point D through a locking pin. The driving gear in the bevel gear set is fixed coaxially with one output shaft of the differential, the driving gear in the second bevel gear set is coaxially fixed with the other output shaft of the differential, and the rotating shaft is connected with the first bevel gear set The driven gear is coaxially fixed, the locking pin is coaxial and threaded on the driven gear in the second bevel gear set, and the differential is driven by a drive motor fixed on the frame. Release the pin connection at point D, and the second claw can rotate around point C relative to the first claw to realize emergency unlocking.
Description
Technical field [0001] The present invention relates to a claw separation unlocking mechanism based on the differential speed principle, belonging to the field of aviation and aerospace technology. Background [0002] For some products with elongated characteristics, when it is launched or transported, its own stiffness or stability is insufficient, it is necessary to rely on the auxiliary support device to support it, and when it reaches the intended destination, it requires the auxiliary support device to quickly open to achieve the release of the product, and the auxiliary support device is required to have the characteristics of reusability multiple times. [0003] The mechanism that realizes the rapid unlocking and release of the auxiliary support device is defined as the unlocking separation mechanism, and the unlocking separation mechanism needs to ensure that the auxiliary support device is a complete structure in the process of supporting the product, and when unlocked,...
