Description

Technical Field

[0001] This utility model relates to the field of wing technology, specifically to a wing with a support mechanism. Background Technology

[0002] The wing is the core component of an aircraft that generates lift. Its structural design directly affects the aircraft's aerodynamic performance, load-bearing capacity, and flight safety, and it is widely used in various types of aircraft, including civil airliners, military aircraft, and general aviation aircraft. During flight, the wing must withstand its own weight, fuel load, aerodynamic load, and ground impact forces during takeoff and landing. Especially under complex weather conditions or during maneuvering flight, the wing structure will be subjected to severe alternating loads, thus requiring sufficient strength, stiffness, and fatigue resistance.

[0003] With the development of the aviation industry, aircraft are evolving towards larger size, higher speed, and lighter weight, and wing design faces multiple challenges: the wingspan of large civil airliners has exceeded 60 meters, and it is necessary to balance structural weight and load-bearing capacity while ensuring aerodynamic efficiency; military fighter jets, in pursuit of high maneuverability, need wings to withstand loads several times the weight of the fuselage when flying at high angles of attack; and new energy aircraft, due to the installation of batteries and other auxiliary equipment, require wings with more flexible load distribution adaptability.

[0004] For example, Chinese utility model patent application number 201820391229.6 discloses an aerospace-grade aircraft tail fin with an easy-to-disassemble function. The rotation of the motor output end drives the threaded rod to rotate, the threaded rod drives the threaded block to move to the left on the threaded rod, the threaded block drives the plug-in rod to move to the left, and the threaded block drives the positioning block to slide to the left on the positioning rod, so that the plug-in rod disengages from the fixing groove and lifts the vertical tail fin upward, thereby achieving the effect of easy disassembly. However, its device still has certain defects; The lack of a support mechanism for the aircraft tail section causes concentrated stress on the connecting end of the tail section, which significantly exacerbates structural fatigue and safety hazards, poses a serious threat to flight stability, and reduces the service life of the aircraft tail section.

[0005] Therefore, we propose a wing with a support mechanism to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a wing with a support mechanism to solve the problem mentioned in the background art that the tail fins of aircraft currently on the market do not have a support mechanism, which causes the connection end of the tail fin to be subjected to concentrated force, which will significantly aggravate structural fatigue and safety hazards, pose a serious threat to flight stability, and reduce the service life of the tail fin.

[0025] Example 1 Please see Figures 1-4This utility model provides a technical solution: a wing with a support mechanism, including a body 1, a fixing block 2, an internal groove 3, a servo motor 4, a protective box 5, left and right lead screws 6, a slider 7, a guide rod 8, a limiting block 9, a wing body 10, a connecting block 11, a groove 12, a snap-fit ​​groove 13, a reinforcing rib 14, a threaded rod assembly 15, a support bar assembly 16, a fixing nut 17, and a baffle 18. The fixing block 2 is installed on the top of the body 1, and the protective box 5 is installed on the left side of the fixing block 2. The interior of the protective box 5 is provided with... Servo motor 4 is fixed on fixed block 2. The right side of servo motor 4 is connected to left and right lead screws 6 via an output shaft. The protective box 5 on the left side of fixed block 2 protects the internal servo motor 4. Servo motor 4 drives the left and right lead screws 6 to rotate via the output shaft, providing power for the movement of slider 7, realizing the automatic engagement or disengagement of limit block 9 and locking groove 13, facilitating the quick installation and disassembly of wing body 10. The protective box 5 is equipped with a heat dissipation mesh and an inspection door. Servo motor 4 has a waterproof structure design. The heat dissipation mesh of the protective box 5 ensures smooth heat dissipation of servo motor 4 during operation, and the inspection door facilitates motor maintenance. The waterproof structure design of servo motor 4 can resist the influence of humid environment and ensure stable operation under complex weather conditions. The upper surface of fixed block 2 has an internal groove 3. The left and right lead screws 6 are installed in the internal groove 3 via bearing seats, and sliders 7 are installed on both sides of the left and right lead screws 6. Guide rods 8 are installed on both the front and rear sides of the internal groove 3. The guide rods 8 pass through the sliders 7, and the sliders 7 and guide rods 8 are slidably connected. The guide rods 8 in the internal groove 3 pass through the sliders 7. The slider 7 is inserted to restrict it to slide only along the direction of the guide rod 8, so as to prevent the slider 7 from deviating when the left and right lead screws 6 rotate. This ensures that the limiting block 9 is accurately aligned with the locking groove 13. Limiting blocks 9 are installed on the top of the slider 7. The width of the groove 12 is greater than the diameter of the left and right lead screws 6. The limiting blocks 9 on the slider 7 are engaged with the locking groove 13. The groove 12 of the connecting block 11 provides space for the left and right lead screws 6 to avoid structural interference during installation. The limiting blocks 9 on the slider 7 are engaged with the locking groove 13 to realize the installation of the wing body 10.

[0026] A wing body 10 is mounted above the fixing block 2, and a connecting block 11 is installed below the wing body 10. A groove 12 is provided on the upper surface of the connecting block 11, and snap-fit ​​grooves 13 are provided on both the left and right sides of the connecting block 11. Reinforcing ribs 14 are installed on both the front and rear sides of the wing body 10. Threaded rod assemblies 15 are installed on both the front and rear sides of the fixing block 2, and support bar assemblies 16 are connected to the threaded rod assemblies 15. The upper part of the support bar assembly 16 is connected to the wing body 10, and the lower part of the support bar assembly 16 has a horizontal structure design. The lower part of the support bar assembly 16 passes through the threaded rod assembly 15, and a fixing nut 17 is installed on the threaded rod assembly 15. The upper end of the support bar assembly 16 is connected to the wing body 10, and the lower end passes through the threaded rod assembly 15. The support bar assembly 16 is fixed by tightening the fixing nut 17 to form an oblique support structure, which shares the load borne by the wing body 10 and reduces stress concentration at the connection end. A baffle 18 is installed on the lower surface of the wing body 10.

[0027] Example 2 Please see Figures 5-6 This utility model provides a technical solution: a wing with a support mechanism, including a sealing groove 19 and a sealing strip 20. The difference between this embodiment and Embodiment 1 is that: A sealing groove 19 is installed on the upper surface of the fixing block 2, and a sealing strip 20 is installed on the lower surface of the baffle 18. The sealing strip 20 is engaged with the sealing groove 19. When the baffle 18 below the wing body 10 is in contact with the fixing block 2, the sealing strip 20 is engaged with the sealing groove 19 to form a sealing structure, preventing moisture, dust and other substances from entering the connection part, protecting the internal components from corrosion and extending the service life.

[0028] Working principle: When using the wing with the support mechanism, firstly, the mounting base of the wing body 10 is fixed by the fixing block 2 above the fuselage 1. When installing the wing body 10, the groove 12 of the connecting block 11 below it is aligned with the inner groove 3 of the fixing block 2, so that the left and right lead screws 6 are in the space of the groove 12 to avoid structural interference.

[0029] The servo motor 4 inside the protective box 5 is started, which drives the left and right lead screws 6 to rotate through the output shaft. The guide rod 8 in the built-in groove 3 restricts the slider 7 to slide in a straight line, which drives the limit block 9 above the slider 7 to move synchronously, and finally locks into the locking grooves 13 on both sides of the connecting block 11, thus completing the fixation of the wing body 10 and the fixing block 2.

[0030] Meanwhile, the upper end of the support bar assembly 16 is connected to the wing body 10, and the lower end passes through the threaded rod assembly 15 on both sides of the fixing block 2. Tightening the fixing nut 17 makes the support bar assembly 16 form an oblique support, further dispersing the aerodynamic load and its own weight borne by the wing body 10, reducing stress concentration at the connection end. At the same time, the reinforcing ribs 14 on both sides of the wing body 10 enhance its own structural strength.

[0031] When the baffle 18 below the wing body 10 is attached to the fixing block 2, the sealing strip 20 on the lower surface of the baffle 18 is inserted into the sealing groove 19 on the upper surface of the fixing block 2 to form a sealing structure, preventing water vapor and dust from entering the connection part. The heat dissipation mesh of the protective box 5 dissipates heat for the servo motor 4. The inspection door facilitates maintenance. The waterproof design ensures that the motor operates stably under complex weather conditions.

[0032] During disassembly, the servo motor 4 is started in reverse to disengage the limit block 9 from the locking slot 13. Loosening the fixing nut 17 allows the wing body 10 to be removed. This achieves convenient installation, multiple supports, and effective protection in a coordinated manner, thus completing a series of tasks. Content not described in detail in this specification is prior art known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
