[0001] The present invention relates to the field of aerospace technology, and in particular to a folding wing mechanism capable of bearing vibration loads and a working method thereof. Background Art

[0002] With the continuous development of manufacturing technology and space technology, especially the rapid transformation of equipment in the aerospace field, there is an urgent need for a folding-wing mechanism that can withstand large loads in both folded and unfolded states. Due to the limited carrying conditions, there are certain requirements for the quality and space of aerospace vehicles. The folding-wing mechanism is required to be able to withstand large loads in both folded and unfolded states, and have the characteristics of light weight and small size. Therefore, there is an urgent need to develop a folding-wing mechanism that can withstand large loads in both folded and unfolded states.

[0003] The folding wing mechanism that can withstand large loads in both folded and unfolded states is not only required to be able to withstand large loads in both folded and unfolded states, but also needs to ensure the stability and reliability of the mechanism's own movement.

[0004] Existing technical solutions can only achieve the folding action of the carrier-based aircraft when it is stored on the ship. It is difficult to withstand large vibration loads in the folded state and maintain the smooth aerodynamic shape of the wing in the fully deployed state. In addition, due to the large structure of the wing, it is more difficult to fold it. Summary of the Invention

Compared to traditional methods, this method occupies less internal wing space, while also reducing the wing thickness requirement.

[0050] See also Figures 1 to 18 As shown, the present invention provides a folding wing 4 mechanism that withstands vibration loads, comprising: a fixed wing 1, a fixed wing frame 2 is provided on the fixed wing 1, and at least two positioning blocks 3 are provided on the fixed wing frame 2; a folding wing 4, a folding wing frame 5 is provided on the folding wing 4, and a support ear 6 is provided on the folding wing frame 5, and the support ear 6 is provided between two adjacent positioning blocks 3, and the support ear 6 is provided with an L-shaped slide groove 7; a locking mechanism 8 is provided on the fixed wing 1, and the locking mechanism 8 includes a locking assembly 9 and a rotating member 10, and a locking member 11, the locking assembly 9 is provided on the positioning block 3, the rotating member 10 is connected to the locking assembly 9, the locking member 11 is provided at one end of the rotating member 10 away from the locking assembly 9, the locking member 11 has a locking position and an unlocking position, and when the locking member 11 is in the locking position, the locking member 11 is inserted into the locking hole 12 of the support ear 6, and the locking member 11 is locked. When the fastener 11 is in the unlocked position, the locking member 11 moves out of the locking hole 12; the driving mechanism 13 is provided on the positioning block 3, and the driving mechanism 13 includes a driving assembly 14 and a crank 15, a connecting rod 16, and a guide assembly 17. The driving assembly 14 and the guide assembly 17 are both provided on the positioning block 3, the crank 15 is connected to the driving assembly 14, and is located between two adjacent support ears 6, the connecting rod 16 is connected to the crank 15, and the connecting rod 16 is connected to the support ear 6, the driving mechanism 13 rotates, driving the crank 15 and the connecting rod 16 to rotate, the guide assembly 17 slides in the L-shaped slide 7, and drives the support ear 6 and the folding wing 4 to rotate synchronously, the driving mechanism 13 continues to rotate, driving the crank 15 and the connecting rod 16 to continue to rotate, and the folding wing 4 moves parallel to the positioning block 3; the carrying mechanism is provided on the fixed wing frame 2 and the folding wing frame 5.

[0051] By providing at least two positioning blocks 3 on the fixed wing frame 2, a mounting position is provided for the locking mechanism 8 on the fixed wing 1, ensuring the installation stability of the locking mechanism 8. At the same time, a lug 6 is provided on the fixing frame of the folding wing 4, and an L-shaped slot 7 is provided on the lug 6. The locking assembly 9 drives the rotating member 10 to rotate, so that the locking member 11 switches between the locked position and the unlocked position, thereby achieving the connection and separation between the folding wing 4 and the fixed wing 1. By providing a crank 15 between two adjacent positioning blocks 3, and then driving the crank 15 to rotate through the drive assembly 14, the connecting rod 16 is driven to rotate. Since the connecting rod 16 is connected to the lug 6, it can drive the lug 6 to rotate 90 degrees. At the same time, the guide assembly 17 slides in the L-shaped slot 7, thereby driving the folding wing 4 to rotate. At this time, the driving mechanism 13 can continue to rotate, driving the crank 15 and the connecting rod 16 to continue to rotate, so as to realize the parallel movement of the support ear 6 and the folding wing 4 relative to the positioning block 3, and then use the positioning and bearing mechanism 18 on the fixed wing frame 2 and the folding wing frame 5 to realize the positioning and bearing of the fixed wing 1 and the folding wing 4.

[0052] This vibration-load-bearing folding wing 4 mechanism, through the combined action of a locking mechanism 8 and a drive mechanism 13, can withstand significant loads in both the folded and fully deployed states. Simultaneously, the folding mechanism occupies minimal internal wing space and enables smooth, continuous deformation of the wing's aerodynamic shape after full deployment without damaging the wing's surface form. This mechanism can be applied to fairings for spacecraft, reducing envelope volume and increasing payload. Compared to traditional methods, this folding mechanism occupies less internal wing space, while also reducing the wing thickness requirement for the deformation method.

[0053] Furthermore, since the locking mechanism 8 and the driving mechanism 13 are provided on the fixed-wing frame 2 and the folding-wing frame 5, and the L-shaped slot 7 on the support ear 6 cooperates with the guide assembly 17, when the folding wing 4 is folded relative to the fixed wing 1, that is, rotated and moved parallel to the fixed wing 1, it has good reliability and facilitates the movement of the folding wing 4.

[0054] Since the L-shaped slot 7 on the support ear 6 is set to be L-shaped, when the crank 15 rotates, the support ear 6 can be driven to rotate 90° first and then move parallel to each other.

[0055] The folding wing frame 5 is arranged perpendicular to the fixed wing frame 2 .

[0056] In addition, there are four positioning blocks 3, two in each group, which are arranged at intervals on the fixed-wing frame 2. During installation, it is necessary to ensure the synchronization of the installation. Therefore, one side can be installed first, and then the other side can be adjusted and installed.

[0057] In some optional embodiments, the locking assembly 9 includes a support base 19 and a fixing plate 21; wherein the support base 19 is provided on the positioning block 3, and a locking driving member 20 is provided at one end of the support base 19 away from the positioning block 3, and the rotating member 10 is connected to the locking driving member 20, so that the locking driving member 20 drives the rotating member 10 to rotate;

[0058] At the same time, the fixing plate 21 is provided on the rotating member 10, and the locking member 11 is provided on the fixing plate 21. That is, the locking driving member 20 drives the rotating member 10 to rotate, so that the fixing plate 21 moves relative to the support seat 19, thereby driving the fixing plate 21 to move. Since the locking member 11 is provided on the fixing plate 21, the fixing plate 21 moves, so that the locking member 11 can be disengaged from the locking hole 12 of the support ear 6, that is, the support ear 6 is unlocked, thereby facilitating the rotation of the support ear 6.

[0059] When the locking hole 12 needs to be inserted into the locking hole 12 of the support ear 6, the locking driving member 20 is used to drive the rotating member 10 to rotate, so that the fixing plate 21 moves relative to the support seat 19, and then drives the fixing plate 21 to move. Since the locking member 11 is set on the fixing plate 21, the movement of the fixing plate 21 allows the locking member 11 to be inserted into the locking hole 12 of the support ear 6, that is, the support ear 6 is locked, thereby achieving the locking of the support ear 6 and preventing the support ear 6 from moving at will.

[0060] The locking member 11 is a locking pin.

[0061] The positioning block 3 is also provided with a connecting hole 49 , and the setting of the connecting hole 49 is convenient for supporting the locking member 11 .

[0062] Specifically, the rotating member 10 is a screw. Due to the arrangement of the screw, when the screw rotates, the fixed plate 21 can be driven to move. Meanwhile, a nut 37 is also provided on the fixed plate 21, and the nut 37 is sleeved on the screw.

[0063] There are two locking members 11, one at each end of the fixing plate 21. The two locking members 11 are inserted into the two locking holes 12 of the support lug 6 to ensure secure locking. Locking nuts 47 are provided at the ends of the locking members 11 to securely lock the locking members 11 to the fixing plate 21.

[0064] In this embodiment, the locking driving member 20 includes a locking motor 22 and a locking reducer 23 , which are connected in sequence, and a locking coupling 24 . The locking coupling 24 is connected to the rotating member 10 .

[0065] The locking drive component 20 also includes a locking base 38, which is connected to the support base 19. The locking motor 22 and the locking reducer 23 are connected by screws. The locking motor 22 and the locking reducer 23 form an integral part and are arranged on the locking base 38. That is, the locking base 38 is used to support the locking motor 22 and the locking reducer 23, thereby ensuring the stability of the installation of the locking motor 22 and the locking reducer 23.

[0066] Furthermore, the locking coupling 24 is disposed in the locking base 38 , that is, the locking base 38 is used to protect the locking coupling 24 .

[0067] In some optional embodiments, an output shaft 25 is provided on the positioning block 3, the drive assembly 14 is connected to the output shaft 25, and the crank 15 is sleeved on the output shaft 25, thereby realizing the connection between the crank 15 and the output shaft 25, and the output shaft 25 can be driven to rotate by the drive assembly 14, and then the crank 15 can be driven to rotate.

[0068] Among them, there are two cranks 15, which are set close to the positioning block 3. One crank 15 is connected to the drive assembly 14 through the output shaft 25, and the other crank 15 is set on the other positioning block 3 through the positioning shaft 46, thereby realizing the positioning of the other crank 15, and a stop washer 48 is set on the positioning shaft 46, and then locked with a locking nut 47.

[0069] In this embodiment, there are four cranks 15 , two in each group, and they are arranged close to the positioning block 3 .

[0070] There are two supporting ears 6 , which are respectively arranged between the two groups of cranks 15 .

[0071] Specifically, the support ear 6 includes a main body 26 and two bearing seats 27, and a connecting shaft 28. The two bearing seats 27 are symmetrically arranged in the main body 26, and the connecting shaft 28 is located between the two bearing seats 27. The connecting rod 16 is sleeved on the connecting shaft 28, thereby realizing the connection between the connecting rod 16 and the support ear 6. The rotation of the connecting rod 16 can drive the support ear 6, the folding wing frame 5, and the folding wing 4 to rotate.

[0072] In this embodiment, the support ear 6 is in a hook shape, i.e., a J shape. Setting the support ear 6 into a J shape facilitates setting the L-shaped slide groove 7 on the support ear 6. At the same time, L-shaped slide grooves 7 are set on both sides of each support ear 6.

[0073] In some optional embodiments, the connecting rod 16 includes a fixed section 29 and a connecting section 30, the fixed section 29 is provided at one end of the crank 15, the connecting section 30 is connected to the fixed section 29, and a sleeve 31 is provided on the connecting section 30, and the sleeve 31 is sleeved on the connecting shaft 28, thereby realizing the connection between the connecting rod 16 and the support ear 6, that is, the rotation of the connecting rod 16 can drive the support ear 6 and the folding wing frame 5, as well as the folding wing 4 to rotate.

[0074] At the same time, the guide assembly 17 includes a fixed shaft 32 and a bearing 33, as well as a shaft end retaining ring 34. The fixed shaft 32 passes through the positioning block 3, the bearing 33 is sleeved on one end of the fixed shaft 32, and the bearing 33 is located between two adjacent positioning blocks 3, and the shaft end retaining ring 34 is arranged at the other end of the fixed shaft 32.

[0075] By setting the fixed shaft 32 and setting the bearing 33 at one end of the fixed shaft 32, it is convenient to insert the bearing 33 into the L-shaped groove 7 of the support ear 6, which can reduce the friction between the bearing 33 and the support ear 6; at the same time, the setting of the shaft end retaining ring 34 can achieve the locking of the fixed shaft 32.

[0076] Among them, the positioning and supporting mechanism 18 includes a supporting pin 35 and a supporting hole 36, the supporting pin 35 is arranged on one of the fixed wing frame 2 and the folding wing frame 5, and the supporting hole 36 is arranged on the other of the fixed wing frame 2 and the folding wing frame 5, and the supporting pin 35 is inserted into the supporting hole 36 to connect the fixed wing 1 and the folding wing 4.

[0077] The bearing pins 35 can be set on the fixed wing frame 2 and the bearing holes 36 can be set on the folding wing frame 5 to achieve the connection between the fixed wing 1 and the folding wing 4;

[0078] Of course, the bearing holes 36 may also be provided on the fixed-wing frame 2 , and the bearing pins 35 may be provided on the folding-wing frame 5 , thereby achieving the connection between the fixed wing 1 and the folding wing 4 .

The drive motor 39 and the drive reducer 40 are connected by screws. At the same time, the drive reducer 40 is connected to one end of the drive coupling 41, and the other end of the drive coupling 41 is connected to the output shaft 25, thereby realizing the connection between the drive assembly 14 and the output shaft 25.

[0081] At the same time, the folding wing skeleton 5 has multiple folding wings 4, which are fixedly spaced apart. A heat-insulating fixed structure 43 is also provided on the folding wing skeleton 5. The heat-insulating fixed structure 43 includes a titanium alloy adapter frame 44 and a quartz gasket 45. A quartz gasket 45 is provided in the titanium alloy adapter frame 44. The folding wing skeleton 5 is clamped between a pair of quartz gaskets 45 and the titanium alloy adapter frame 44. The four sides are mechanically connected by bolts and secured to prevent loosening. The support ears 6 are welded to the titanium alloy adapter frame 44 and fixedly connected. An oblong hole is provided on the lower titanium alloy adapter frame 44 for precision control.

[0082] The heat-insulating fixing structure 43 is mainly used to prevent the heat load of the wing surface from being transferred to the folding mechanism, thereby playing a role of heat insulation.

[0083] In this embodiment, there are three folding wing frames 5 , which are arranged at intervals. The first folding wing frame 5 and the second folding wing frame 5 are provided with a heat insulation fixing structure 43 , and the third folding wing frame 5 is provided with two supporting ears 6 .

[0084] The present invention also provides a folding wing 4 mechanism capable of bearing vibration loads, comprising:

[0085] When the folding wing 4 needs to be folded, the locking assembly 9 drives the rotating member 10 to rotate, and drives the locking member 11 to move from the locked position to the unlocked position, and the locking member 11 moves out of the locking hole 12. Then, the driving mechanism 13 rotates forward, drives the crank 15 and the connecting rod 16 to rotate, and drives the ear 6 and the folding wing 4 to rotate synchronously, and the folding wing 4 changes from a vertical state to a horizontal state. The driving mechanism 13 continues to rotate, drives the crank 15 and the connecting rod 16 to continue to rotate, and the ear 6 and the folding wing 4 move parallel to the positioning block 3. The positioning bearing mechanism 18 on the fixed wing 1 and the folding wing 4 is connected;

[0086] When the folding wing 4 needs to be unfolded, the driving mechanism 13 rotates in the opposite direction, the positioning and bearing mechanisms 18 on the fixed wing 1 and the folding wing 4 are separated, driving the crank 15 and the connecting rod 16 to rotate, and the support ear 6 and the folding wing 4 move parallel to the positioning block 3. The driving mechanism 13 continues to rotate, driving the crank 15 and the connecting rod 16 to continue to rotate, and driving the support ear 6 and the folding wing 4 to rotate synchronously, and the folding wing 4 changes from a horizontal state to a vertical state. The locking assembly 9 drives the rotating member 10 to rotate, and drives the locking member 11 to move from the unlocked position to the locked position, and the locking member 11 is inserted into the locking hole 12.

[0087] The specific steps are:

[0088] Step 1: The locking motor 22 drives the rotating member 10 to pull the locking member 11 out of the locking hole 12 of the support ear 6;

[0089] The locking motor 22 outputs power to drive the locking reducer 23. The locking reducer 23 drives the rotating member 10 to rotate through the locking coupling 24. The rotation of the rotating member 10 drives the nut 37 to move horizontally. The nut 37 is fixedly connected to the locking member 11 through the fixed plate 21. The nut 37 moves horizontally to drive the locking member 11 to move outward, thereby pulling out the locking member 11.

[0090] Step 2: The driving motor 39 drives the crank 15 to drive the connecting rod 16 and the support lug 6 to start moving;

[0091] The drive motor 39 outputs power to drive the reducer 40, which drives the output shaft 25 through the drive coupling 41. The output shaft 25 drives the crank 15 to rotate via the flat key. A revolving pair is formed between the crank 15 and the connecting rod 16, which drives the connecting rod 16 to move. A revolving pair is formed between the connecting rod 16 and the support lug 6, providing power for the movement of the support lug 6. Because the bearing 33 is inserted into the L-shaped slide 7 and utilizes the guiding effect of the bearing 33, the support lug 6 can first rotate 90° and then move parallel. Since the support lug 6 is fixedly connected to the folding wing frame 5, the movement of the support lug 6 drives the folding wing 4 to rotate 90° and then move parallel. The bearing hole 36 on the folding wing frame 5 cooperates with the bearing pin 35 on the fixed wing frame 2 to complete the deployment.

[0092] Step 3: The locking motor 22 drives the rotating member 10 to drive the locking member 11 to insert into the locking hole 12 of the ear 6

[0093] The locking motor 22 outputs power to drive the locking reducer 23. The locking reducer 23 drives the rotating member 10 to rotate through the locking coupling 24. The rotation of the rotating member 10 drives the nut 37 to move parallel. The nut 37 is fixedly connected to the locking member 11 through the fixed plate 21. The nut 37 moves parallel to drive the locking member 11 to move inward, and the locking member 11 is inserted into the locking hole 12 of the support ear 6 and locked.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
