Description

Technical Field

[0001] The utility model belongs to the field of folding wings, and in particular relates to a folding wing mechanism with safety features. Background Art

[0002] Currently, folding wing mechanisms have been applied to many domestic products. However, they are rarely used in general-purpose aircraft, and due to their structural and performance limitations, they have the following drawbacks:

[0003] 1. It occupies a large volume and is not convenient to be installed in a cabin structure with limited space.

[0004] 2. The unfolding speed of the folding wings is unstable and the unfolding synchronization cannot meet the requirements.

[0005] 3. It cannot be locked effectively when working at high speed in the air, and the structure is unstable. Utility Model Content

[0006] The purpose of the utility model is to provide a folding wing mechanism with a safety feature to solve the problems of unstable unfolding speed of the folding wings, inability to effectively lock them, and low stability.

[0007] In order to solve the above problems, the utility model discloses a folding wing mechanism with security, including an intermediate bottom and folding wings hingedly mounted on the intermediate bottom. The number of folding wings can be set as needed and needs to be symmetrically and evenly distributed. The intermediate bottom is connected to an outer shell, and a slot is provided on the outer shell so that the folding wings extend from the slot. A clamp is provided on the outside of the outer shell, and the folding wings are constrained in the outer shell by the clamp; an unfolding component, a locking component and a switch component are also provided on the intermediate bottom. The unfolding component is used to unfold the folding wings, the locking component is used to lock the unfolded folding wings, and the switch component is used to feedback signals.

[0008] As a further improvement of the above technical solution:

[0009] The unfolding assembly includes a wing shaft, a sleeve, an unfolding torsion spring and a first mounting nut. The wing shaft is installed on the middle bottom, and the sleeve is rotatably installed on the wing shaft. The folding wing is connected to the sleeve. The unfolding torsion spring is installed on the wing shaft. The first mounting nut is installed on the wing shaft to limit the unfolding torsion spring. One end of the unfolding torsion spring is supported on the middle bottom, and the other end is supported on the folding wing. When the folding wing is in the retracted state, the unfolding torsion spring is tightened by force. When the restraining force of the clamp is removed, the folding wing is unfolded by the action of the unfolding torsion spring.

[0010] The locking assembly includes a locking block, a locking shaft, a locking torsion spring and a second mounting nut. The locking shaft is installed on the middle bottom, and the locking block is rotatably engaged with the locking shaft. The locking torsion spring is installed on the locking shaft and is limited by the second mounting nut. When the folding wing is in the retracted state, the locking torsion spring is forced to drive the locking block close to the folding wing. When the restraining force of the clamp is removed and the folding wing is unfolded, the locking block is no longer constrained by the folding wing and is quickly driven by the locking torsion spring to reach the locking position, thereby locking the folding wing.

[0011] The switch assembly includes a switch seat, a folding wing switch, a signal line and mounting screws. The switch seat is installed on the middle bottom by the mounting screws. When the folding wings are retracted, the folding wing switch is in a free state and does not trigger a signal; when the folding wings are unfolded, the folding wings are unfolded, the folding wing switch is pressurized, and a trigger signal is issued, and the signal is transmitted to the control cabin through the signal line.

[0012] The switch assembly includes two groups that are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Automatic deployment and locking: After the constraints are released, the folding wings can automatically and quickly deploy by relying on the deployment torsion springs, and can be quickly locked by locking the torsion springs, thereby improving the deployment efficiency and safety of the aircraft.

[0015] Safety Assurance: The folding wing switch triggers a signal when the folding wings are unfolded, ensuring that the security system is unlocked only after the aircraft's folding wings are fully unfolded, thus avoiding flight risks caused by incomplete folding wings.

[0016] Stability: The locking function of the folding wing mechanism ensures the firm fixation of the wings and improves the flight stability of the aircraft.

[0017] Signal feedback: The switch component can provide real-time feedback on the deployment status of the folding wings, providing a decision-making basis for the aircraft control system and ensuring that the aircraft operates in a safe state.

[0018] Compact structure: The folding wing mechanism designed in this utility model has a compact structure, is easy to install and maintain, and reduces the overall weight and volume of the aircraft.

[0019] Space saving: The folding wing design makes the aircraft take up less space during storage and transportation, improving space utilization.

[0020] Improve work efficiency: Automatic deployment and locking functions reduce the number of operating steps and improve the efficiency of aircraft preparation.

[0021] Enhanced safety: Through the optimized design of the folding wing mechanism, the aircraft is provided with more reliable safety protection and the risk of accidents is reduced.

[0022] In summary, the folding wing mechanism is accommodated within a limited cabin volume using a structural optimization design approach. High-speed deployment technology ensures reliable and stable deployment of the folding wing mechanism in the shortest possible time, while also achieving a highly reliable mechanical locking design. The folding wing switch design ensures high safety and reliability for the aircraft's security system. This solves the issues of unstable folding wing deployment speed, ineffective locking, and low stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figure 1 and Figure 2 As shown, the folding wing mechanism with a safety feature in this embodiment includes a center base 4 and a folding wing 13 hingedly mounted on the center base 4. The center base 4 is connected to a housing 1, which has a slot formed in the housing 1, through which the folding wing 13 extends. A clamp 12 is provided on the outside of the housing 1 to constrain the folding wing 13 within the housing 1. Also provided on the center base 4 are an unfolding assembly 2, a locking assembly 3, and a switch assembly 6. The unfolding assembly 2 is used to unfold the folding wing 13, and the locking assembly 3 is used to lock the unfolded folding wing 13. The switch assembly 6 includes two symmetrically distributed groups. The switch assembly 6 is used to provide feedback signals.

[0037] like Figure 3 and Figure 4As shown, the unfolding assembly 2 includes a flap shaft 16, a sleeve 14, an unfolding torsion spring 17 and a first mounting nut 15. The flap shaft 16 is installed on the middle bottom 4. The sleeve 14 is rotatably installed on the flap shaft 16. The folding flap 13 is connected to the sleeve 14. The unfolding torsion spring 17 is installed on the flap shaft 16. The first mounting nut 15 is installed on the flap shaft 16 to limit the unfolding torsion spring 17. One end of the unfolding torsion spring 17 is supported on the middle bottom 4, and the other end is supported on the folding flap 13. When the folding flap 13 is in a retracted state, the unfolding torsion spring 17 is tightened by force. When the restraining force of the clamp 12 is removed, the folding flap 13 is unfolded by the action of the unfolding torsion spring 17.

[0038] like Figures 5 to 7 As shown, the locking assembly 3 includes a locking block 18, a locking shaft 19, a locking torsion spring 20 and a second mounting nut 21. The locking shaft 19 is installed on the middle bottom 4. The locking block 18 is rotatably fitted on the locking shaft 19. The locking torsion spring 20 is installed on the locking shaft 19 and is limited by the second mounting nut 21. When the folding flap 13 is in the retracted state, the locking torsion spring 20 is forced to drive the locking block 18 close to the folding flap 13. When the restraining force of the clamp 12 is removed, the folding flap 13 is unfolded, and the locking block 18 is no longer constrained by the folding flap 13. It is driven by the locking torsion spring 20 to quickly reach the locking position, thereby locking the folding flap 13.

[0039] like Figure 8 As shown, the switch assembly 6 includes a switch base 24, a folding wing switch 23, a signal line 25 and a mounting screw 7. The switch base 24 is mounted on the middle bottom 4 by the mounting screw 7. When the folding wing 13 is in the retracted state, the folding wing switch 23 is in a free state and does not trigger a signal; when the folding wing 13 is unfolded, the folding wing switch 23 is compressed, sends a trigger signal, and transmits the signal to the control cabin through the signal line 25.

[0040] When in use, the restriction of the clamp 12 is released, and the folding wing 13 is quickly unfolded under the action of the unfolding torsion spring 17. At the same time, the locking torsion spring 20 drives the locking block 18 to combine with the limiting part of the folding wing 13 to lock the folding wing 13. When the folding wing 13 is unfolded, the folding wing switch 23 on the switch seat 24 is squeezed, and the switch signal is input into the control cabin through the signal line. The switch assembly serves as a protection circuit on the aircraft and provides decision-making for the control system on the aircraft. Only when the switch on the aircraft transmits the wing deployment signal and the security system on the aircraft is unlocked, the control system on the aircraft begins to officially work.

[0041] The utility model's secure folding wing mechanism, once the constraints on the folding wing mechanism are removed, the folding wings of the deployment assembly are driven by the deployment torsion spring, causing them to rapidly deploy. Simultaneously, the locking torsion spring of the locking assembly drives the locking block to the locked position, securing the folding wings. The folding wing switch is triggered when the folding wings deploy, transmitting a deployment signal to the control cabin, unlocking the aircraft's security system and providing input to the aircraft's control system, thus ensuring the safety of the entire system. The folding wing mechanism not only implements the deployment and locking function of the folding wing compartment, ensuring the aircraft's flight stability, but also provides overall safety assurance for the aircraft system.

[0042] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claim involved.
