Description

Technical Field

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

[0002] At present, the folding wing mechanism has been applied to many domestic products. However, the folding wing mechanism for general-purpose aircraft is rarely used, and due to its structural and performance limitations, it has the following defects:

[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. Summary of the invention

[0006] The purpose of the present invention is to provide a folding wing mechanism with safety features 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 present invention discloses a folding-wing mechanism with security, comprising a middle bottom and folding wings hingedly mounted on the middle bottom, the number of folding wings can be set as needed and must be symmetrically and evenly distributed, the middle bottom is connected to an outer shell, a slot is provided on the outer shell so that the folding wings extend from the slot, a clamp is provided outside the outer shell, and the folding wings are constrained in the outer shell by the clamp; an unfolding assembly, a locking assembly and a switch assembly are also provided on the middle bottom, the unfolding assembly is used to unfold the folding wings, the locking assembly is used to lock the unfolded folding wings, and the switch assembly 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, and 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 a retracted state, the unfolding torsion spring is tightened by force. When the binding 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 fitted on 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 a 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 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 compressed, 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 which are symmetrically distributed.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Automatic deployment and locking: After the constraints are released, the folding wings can be automatically and quickly deployed by relying on the deployment torsion springs, and can be quickly locked by locking the torsion springs, which improves 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 can only be unlocked 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 wing and improves the flight stability of the aircraft.

[0017] Signal feedback: The switch component can provide real-time feedback on the unfolding 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 the present invention 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: The automatic deployment and locking function reduces the operation links and improves 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 general, the structural optimization design method is adopted to install the folding wing mechanism in a limited cabin. The high-speed deployment design technology can reliably and stably deploy the folding wing mechanism in the shortest time and realize the high-reliability mechanical structure locking design. The folding wing switch design can realize the high safety and reliability of the security system on the aircraft. The problems of unstable deployment speed, ineffective locking and low stability of the folding wings are solved. BRIEF DESCRIPTION OF THE DRAWINGS

For example, "connected" can be 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] like Figure 1 and Figure 2 As shown, the folding wing mechanism with security of this embodiment includes a middle bottom 4 and a folding wing 13 hingedly mounted on the middle bottom 4. The middle bottom 4 is connected to a shell 1. A slot is provided on the shell 1 so that the folding wing 13 extends out of the slot. A clamp 12 is provided outside the shell 1 to constrain the folding wing 13 in the shell 1. An unfolding assembly 2, a locking assembly 3 and a switch assembly 6 are also provided on the middle bottom 4. The unfolding assembly 2 is used to unfold the folding wing 13. 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 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 mounted on the middle bottom 4, the sleeve 14 is rotatably mounted on the flap shaft 16, the folding flap 13 is connected to the sleeve 14, the unfolding torsion spring 17 is mounted on the flap shaft 16, and the first mounting nut 15 is mounted on the flap shaft 16 to achieve the limiting of 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 wing 13 is in the retracted state, the locking torsion spring 20 is forced to drive the locking block 18 close to the folding wing 13. When the restraining force of the clamp 12 is removed, the folding wing 13 is unfolded, and the locking block 18 is no longer constrained by the folding wing 13. It is driven by the locking torsion spring 20 to quickly reach the locking position and lock the folding wing 13.

[0039] like Figure 8 As shown, the switch assembly 6 includes a switch seat 24, a folding wing switch 23, a signal line 25 and a mounting screw 7. The switch seat 24 is mounted on the middle bottom 4 by means of the mounting screw 7. When the folding wing 13 is in a 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, a trigger signal is issued, and the signal is transmitted 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 achieve the locking of 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 a wing unfolding signal and the security system on the aircraft is unlocked, the control system on the aircraft begins to work officially.

[0041] The folding wing mechanism with security of the present invention, once the constraint on the folding wing mechanism is removed, the folding wing of the unfolding assembly is driven by the unfolding torsion spring, and the folding wing is quickly unfolded; at the same time, the locking torsion spring of the locking assembly drives the locking block to the locking position quickly, so that the folding wing is firmly locked; the folding wing switch is triggered when the folding wing is unfolded, and the unfolding signal is transmitted to the control cabin, unlocking the security system on the aircraft, and providing input to the control system on the aircraft, providing security for the entire system. The folding wing mechanism not only realizes the unfolding and locking function of the folding wing cabin, ensuring the flight stability performance of the aircraft, but also provides security for the overall safety of the aircraft system.

[0042] The above is only an embodiment of the present invention, and the common sense such as the known specific structure and characteristics in the scheme is 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, and the scope of the present invention is defined by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
