[0029] like Figures 1 to 8As shown, a locking release mechanism is provided according to a specific embodiment of the present invention. The locking release mechanism includes a housing 10, an elastic element fixing rod 20, a rotating shaft 30, an assisting elastic element 40, a locking hook 50, and a locking force-bearing element 60. The housing 10 has a receiving cavity 10a, a slot 10b, and a locking hole. The slot 10b is used to receive a hanging device connector. The elastic element fixing rod 20 and the rotating shaft 30 are fixedly arranged at intervals within the receiving cavity 10a. The assisting elastic element 40 is disposed within the receiving cavity 10a. One of the assisting elastic elements 40... The end is connected to the elastic element fixing rod 20, and the locking hook 50 is disposed in the receiving cavity 10a. The locking hook 50 can rotate around the rotating shaft 30. The locking hook 50 is connected to the other end of the assisting elastic element 40. The locking hook 50 includes a first locking hook section 51, a second locking hook section 52, and a third locking hook section 53 connected in sequence. The first locking hook section 51 and the third locking hook section 53 are arranged in parallel. The length of the first locking hook section 51 is greater than the length of the third locking hook section 53. The locking force-bearing element 60 is movable along the height direction of the housing 10 (the height direction is perpendicular to the locking hook rotation plane). The locking force-bearing element 60 can selectively engage with the locking hole, and the locking force-bearing element 60 can abut against the first locking hook section 51 to restrict the rotation of the first locking hook section 51; wherein, when the locking release mechanism is used to lock the hanging device, the locking force-bearing element 60 engages with the locking hole, inserting the hanging device connector into the slot 10b, and the locking hook 50 rotates around the first direction under the drive of the hanging device connector; when the hanging device connector reaches the set position, the locking hook 50 separates from the hanging device connector, and the assist elastic element 40... Under the action of the first direction, the locking hook 50 rotates around the second direction. When the third locking hook section 53 is located at the lower part of the hanging device joint, the hanging device is lowered, and the locking hook 50 abuts against the locking bearing element 60 to complete the locking of the hanging device. When the hanging device is released using the locking release mechanism, the locking bearing element 60 moves along the height direction of the housing 10, and the locking bearing element 60 separates from the locking hole. Under the action of the weight of the hanging device, the locking hook 50 rotates around the second direction to complete the release of the hanging device. The first direction and the second direction are opposite.

[0030] This configuration provides a locking and releasing mechanism. This mechanism includes an assisting elastic element, a locking hook, and a locking force-bearing element. When the suspension device is locked using the locking and releasing mechanism, the locking force-bearing element 60 engages with the locking hole, inserting the suspension device connector into the slot 10b, and the locking hook 50 rotates in a first direction. When the suspension device connector reaches a set position, under the action of the assisting elastic element 40, the locking hook 50 rotates in a second direction. When the third locking hook section 53 is located at the lower part of the suspension device connector, the suspension device is lowered, and the locking hook 50 abuts against the locking force-bearing element 60, completing the locking of the suspension device. When the suspension device is released using the locking and releasing mechanism, the locking force-bearing element 60 moves along the height direction of the housing 10, separating from the locking hole. The locking hook 50 rotates in a second direction under the weight of the suspension device, completing the release of the suspension device. Compared with the prior art, the locking and releasing mechanism provided by this invention achieves rapid locking and unlocking through the insertion and removal action of a rotating locking hook installed in the housing and a locking force-bearing element in its vertical direction. The bent rotating locking hook helps to reduce the overall size and weight of the locking and releasing mechanism. The locking force-bearing element installed in the vertical direction of its rotation plane ensures the rapid and reliable locking and unlocking of the locking hook. In addition, there is an auxiliary elastic element as an aid to the locking hook in completing the locking and unlocking action. This structure is simple in structure, small in size, light in weight, and easy to operate. It can meet the rapid locking and unlocking requirements of a certain hoisting device, and complete the rapid mounting, unloading or jettisoning of the hoisting device on the aircraft. It can effectively eliminate the fatal impact of the hoisting device on the flight of the UAV in case of emergencies.

[0031] Specifically, the sling device contacts the locking release mechanism through the sling device connector 100. The sling device connector 100 is generally a cylindrical rod with hooks at both ends, through which the suspended weight is connected. When locking the sling device using the locking release mechanism, first, the locking release mechanism is fixed to the corresponding aircraft position where the sling device needs to be installed, and then the locking load-bearing element 60 is inserted into the locking hole on the housing 10. Figure 1 and Figure 2As shown (the hanging device connector 100 shown in the figure is a cross-sectional view of the hanging device connector 100), the hanging device connector 100 is slowly inserted vertically into the slot 10b. During the insertion process, the hanging device connector 100 exerts a squeezing force on the locking hook, causing the locking hook 50 to rotate around the first direction (in this embodiment, the first direction is clockwise). When the hanging device connector reaches the set position, that is, when the hanging device connector 100 enters the top position of the slot 10b and disengages from the locking hook 50, the locking hook 50 rotates around the second direction (in this embodiment, the second direction is counterclockwise) under the action of the assisting elastic element 40. When the third locking hook section 53 is located at the lower part of the hanging device connector 100, the hanging device is lowered. At this time, under the gravity of the hanging device, the locking hook 50 continues to rotate around the second direction until the locking hook 50 abuts against the locking bearing element 60. At this time, the locking hook 50 no longer rotates, and the hanging device is suspended on the locking hook, completing the locking of the hanging device. Specifically, as shown in the figure... Figure 3 and Figure 4 As shown.

[0032] When releasing the suspension device using the locking release mechanism, the locking bearing element 60 is first driven to move along the height direction of the housing 10 until the locking bearing element 60 separates from the locking hole. Under the weight of the suspension device, the locking hook 50 rotates in the second direction. After rotating a certain angle, since the lower end of the locking hook is open, the suspension device connector disengages from the locking hook, completing the release of the suspension device. Specifically, as follows... Figure 5 and Figure 6 As shown. After the suspension device is released, the assisting elastic element 40 will return to its original state. Under the action of the assisting elastic element 40, the locking hook 50 rotates around the first direction until it stops at the position shown. Figure 7 and Figure 8 It is currently in a position to await the next lifting of heavy objects.

[0033] Furthermore, in this invention, since the locking release mechanism is a semi-enclosed housing, to prevent the assisting elastic element from becoming entangled or in other positions after the movement ends, thus failing to return to its original position, the locking release mechanism can be configured to also include a manual positioning rod 70. The manual positioning rod 70 is disposed on the first locking hook section 51, and the other end of the assisting elastic element 40 is connected to the manual positioning rod 70. The housing 10 also has an arc-shaped guide groove 10c, along which the manual positioning rod 70 can move. The manual guide rod is used to manually drive the locking hook 50 to rotate. In this configuration, by setting the manual positioning rod 70, if the assisting elastic element becomes entangled or in other positions after the movement ends, thus failing to return to its original position, the assisting elastic element can be restored to its initial position by manipulating the manual positioning rod from the outside of the housing.

[0034] In one specific embodiment of the present invention, the assisting elastic element 40 includes a spring. Considering structural load-bearing requirements, the locking load-bearing element 60 includes a locking steel pin. Furthermore, to facilitate the movement of the locking load-bearing element, the locking release mechanism can be configured to also include a drive switch, which is used to drive the locking load-bearing element 60 to move along the height direction of the housing 10.

[0035] Furthermore, in this invention, the housing 10 includes a base 11 and a top cover 12, which are connected by screws.

[0036] According to another aspect of the present invention, a locking and releasing method is provided, which uses the locking and releasing mechanism as described above. The locking and releasing method includes: when locking the hanging device using the locking and releasing mechanism, the locking bearing element 60 engages with the locking hole, inserting the hanging device connector into the slot 10b, and the locking hook 50 rotates about a first direction under the drive of the hanging device connector; when the hanging device connector reaches a set position, the locking hook 50 separates from the hanging device connector, and under the action of the assisting elastic element 40, the locking hook 50 rotates about a second direction; when the third locking hook section 53 is located at the lower part of the hanging device connector, the hanging device is lowered, and the locking hook 50 abuts against the locking bearing element 60, completing the locking of the hanging device; when releasing the hanging device using the locking and releasing mechanism, the locking bearing element 60 moves along the height direction of the housing 10, the locking bearing element 60 separates from the locking hole, and the locking hook 50 rotates about a second direction under the action of the weight of the hanging device, completing the release of the hanging device.

[0037] This configuration provides a locking and releasing mechanism. This mechanism includes an assisting elastic element, a locking hook, and a locking force-bearing element. When the suspension device is locked using the locking and releasing mechanism, the locking force-bearing element 60 engages with the locking hole, inserting the suspension device connector into the slot 10b, and the locking hook 50 rotates in a first direction. When the suspension device connector reaches a set position, under the action of the assisting elastic element 40, the locking hook 50 rotates in a second direction. When the third locking hook section 53 is located at the lower part of the suspension device connector, the suspension device is lowered, and the locking hook 50 abuts against the locking force-bearing element 60, completing the locking of the suspension device. When the suspension device is released using the locking and releasing mechanism, the locking force-bearing element 60 moves along the height direction of the housing 10, separating from the locking hole. The locking hook 50 rotates in a second direction under the weight of the suspension device, completing the release of the suspension device. Compared with the prior art, the locking and releasing mechanism provided by this invention achieves rapid locking and unlocking functions through the insertion and removal action of a rotating locking hook installed in the housing and a locking force-bearing element in its vertical direction. The bent rotating locking hook helps to reduce the overall size and weight of the locking and releasing mechanism. The locking force-bearing element installed in the vertical direction of its rotation plane can ensure the fast and reliable locking and unlocking of the locking hook. In addition, there is an auxiliary elastic element as an aid to the locking hook in completing the locking and unlocking action. This structure is simple in structure, small in size, light in weight, and easy to operate, and can meet the rapid locking and unlocking requirements of a certain hanging device.

[0038] According to another aspect of the present invention, an aircraft is provided, the aircraft including a locking release mechanism and a sling device, the locking release mechanism being the locking release mechanism as described above, and the sling device being connected to the aircraft via the locking release mechanism.

[0039] This configuration provides an aircraft in which the sling device is connected to the aircraft via a locking and releasing mechanism. The locking and releasing mechanism provided by this invention achieves rapid locking and unlocking through the insertion and removal of a rotating hook installed within the housing and a locking force-bearing element in its vertical direction. The bent rotating hook helps reduce the overall size and weight of the locking and releasing mechanism. The locking force-bearing element installed in the vertical direction of its rotation plane ensures rapid and reliable locking and unlocking of the hook. An auxiliary elastic element assists the hook in completing the locking and unlocking actions. This structure is simple, small in size, lightweight, and easy to operate, meeting the rapid locking and unlocking requirements of a sling device. Therefore, using this locking and releasing mechanism in an aircraft can achieve the aircraft's need for rapid locking and unlocking of the sling device, improving the aircraft's performance.

[0040] Furthermore, in this invention, considering that some sling devices are too heavy and bulky, in order to achieve locking and releasing of the sling devices more reliably and stably, the aircraft can be configured to include multiple locking and releasing mechanisms, and the sling devices are connected to the aircraft through multiple locking and releasing mechanisms.

[0041] To gain a further understanding of the present invention, the following description is provided. Figures 1 to 8 The locking and releasing mechanism provided by the present invention will be described in detail.

[0042] like Figures 1 to 8 As shown, a locking and releasing mechanism is provided according to a specific embodiment of the present invention. The locking and releasing mechanism includes a housing 10, an elastic element fixing rod 20, a rotating shaft 30, an assisting elastic element 40, a locking hook 50, a locking force-bearing element 60, and a manual positioning rod 70. The housing 10 has a receiving cavity 10a, a slot 10b, and a locking hole. The slot 10b is used to receive the hanging device connector. The elastic element fixing rod 20 and the rotating shaft 30 are fixedly arranged at intervals within the receiving cavity 10a. The assisting elastic element 40 is disposed within the receiving cavity 10a. The function of the assisting elastic element 40 is to promptly assist the locking hook to spring to the locking position after the hanging device is pushed into the opening of the quick locking and unlocking mechanism and disengaged from the locking hook. One end of the assisting elastic element 40 is connected to the elastic element fixing rod 20. The locking hook 50 is disposed within the receiving cavity 10a. The locking hook 50 is the direct part of the locking and unlocking suspension device. The locking hook 50 can rotate flexibly around the pivot 30. The locking hook 50 is connected to the other end of the assisting elastic element 40. The locking hook 50 includes a first locking hook section 51, a second locking hook section 52 and a third locking hook section 53 connected in sequence. The first locking hook section 51 and the third locking hook section 53 are arranged in parallel. The length of the first locking hook section 51 is greater than the length of the third locking hook section 53. The locking force-bearing element 60 serves as the safety part of the unlocking mechanism. It needs to be driven in the direction perpendicular to the plane of the locking hook rotation and is not affected by the force on the plane of rotation. The locking force-bearing element 60 is movable along the height direction of the housing 10. The locking force-bearing element 60 can be selectively matched with the locking hole. The locking force-bearing element 60 can abut against the first locking hook section 51 to restrict the rotation of the first locking hook section 51. A manual positioning rod 70 is mounted on the first locking hook section 51, and the other end of the assisting elastic element 40 is connected to the manual positioning rod 70. The housing 10 also has an arc-shaped guide groove 10c, along which the manual positioning rod 70 can move. The manual guide rod is used to manually rotate the locking hook 50, and the manual positioning rod 70 can manually push the locking hook into the correct position if the assisting elastic element has not pulled the locking hook into place. In this embodiment, the assisting elastic element is an assisting spring, and the locking force-bearing element 60 is a locking pin.

[0043] In this embodiment, the sling device contacts the locking release mechanism via the sling device connector 100. The sling device connector 100 is generally a cylindrical rod with hooks at both ends, through which the suspended weight is connected. When locking the sling device using the locking release mechanism, firstly, four screws are used to fix the locking release mechanism to the corresponding aircraft position where the sling device needs to be installed, and then the locking pin controlled by the switch is inserted into the locking hole on the housing 10. At this time, the quick-locking release mechanism is in the [position missing]. Figure 7 and Figure 8 The equilibrium position is shown. Next, as... Figure 1 and Figure 2 As shown (the hanging device connector 100 shown in the figure is a cross-sectional view of the hanging device connector 100), the hanging device connector 100 is slowly inserted vertically into the slot 10b and pushed upwards along the slot direction. During the insertion process, the hanging device connector 100 exerts a squeezing force on the locking hook, causing the locking hook 50 to rotate around the first direction (in this embodiment, the first direction is clockwise). When the hanging device connector reaches the top of the slot, the hanging device connector disengages from the locking hook 50. At this time, under the action of the assisting elastic element 40, the locking hook 50 rotates around the second direction (in this embodiment, the second direction is counterclockwise). When the third locking hook section 53 is located at the lower part of the hanging device connector 100, the hanging device is lowered. At this time, under the action of the gravity of the hanging device, the locking hook 50 continues to rotate around the second direction until the locking hook 50 abuts against the locking pin. At this time, the locking hook 50 no longer rotates, and the hanging device is suspended on the locking hook, completing the locking of the hanging device. Specifically, as shown in the figure... Figure 3 and Figure 4 As shown.

[0044] When releasing the suspension device using the locking release mechanism, the switch first controls the locking pin to move along the height direction of the housing 10 until the locking pin separates from the locking hole. The locking pin is then pulled out, and the locking hook 50 rotates in the second direction under the weight of the suspension device. After rotating a certain angle, because the lower end of the locking hook is open, the suspension device connector disengages from the locking hook, completing the release of the suspension device. Specifically, as follows... Figure 5 and Figure 6 As shown. After the suspension device is released, the assisting elastic element 40 returns to its original state. Under the action of the assisting elastic element 40, the locking hook 50 rotates around the first direction to return to the equilibrium position and stays there. Figure 7 and Figure 8 It is currently in a position to await the next lifting of heavy objects.

[0045] In summary, the present invention provides a locking and releasing mechanism. This mechanism comprises an assisting elastic element, a locking hook, and a locking force-bearing element. When the lifting device is locked using the locking and releasing mechanism, the locking force-bearing element 60 engages with the locking hole, inserting the lifting device connector into the slot 10b, and the locking hook 50 rotates around a first direction. When the lifting device connector reaches a set position, under the action of the assisting elastic element 40, the locking hook 50 rotates around a second direction. When the third locking hook section 53 is located at the lower part of the lifting device connector, the lifting device is lowered, and the locking hook 50 abuts against the locking force-bearing element 60, completing the locking of the lifting device. When the lifting device is released using the locking and releasing mechanism, the locking force-bearing element 60 moves along the height direction of the housing 10, separating from the locking hole. The locking hook 50 rotates around the second direction under the action of the weight of the lifting device, completing the release of the lifting device. Compared with existing technologies, the locking and releasing mechanism provided by this invention achieves rapid locking and unlocking through the insertion and removal of a rotating hook installed within the housing and a locking force-bearing element in its vertical direction. The bent rotating hook helps reduce the overall size and weight of the locking and releasing mechanism, while the locking force-bearing element installed in the vertical direction of its rotation plane ensures rapid and reliable locking and unlocking of the hook, guaranteeing the reliable and stable fixation of a UAV sling device under normal conditions and its instantaneous disengagement in emergencies. An auxiliary elastic element assists the hook in completing the locking and releasing actions. This structure is simple in structure, small in size, light in weight, and easy to operate, meeting the rapid locking and unlocking requirements of a sling device. It enables the rapid mounting, unmounting, or jettisoning of the sling device on the aircraft, effectively eliminating the fatal impact of the sling device on UAV flight in emergencies.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
