The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] Example 1

[0045] Please refer to Figure 1-Figure 11 A schematic diagram of a folding wing unlocking device provided in this application includes:

[0046] A hoop assembly, the hoop assembly comprising a first hoop body 1 and a second hoop body 2, wherein an embracing space for embracing the elastic body is formed between the first hoop body 1 and the second hoop body 2; a mounting portion 3 for mounting the folding wing is provided on the first hoop body 1 or the second hoop body 2;

[0047] A connecting assembly 4, wherein the connecting assembly 4 is installed between the first hoop body 1 and the second hoop body 2, and the connecting assembly 4 has a first state and a second state; when the connecting assembly 4 is in the first state, the first hoop body 1 and the second hoop body 2 are locked; when the connecting assembly 4 is in the second state, the first hoop body 1 and the second hoop body 2 are unlocked, so that the folding wing is separated from the projectile body;

[0048] A driving component, wherein the driving component is connected to the connecting component 4 and is used for switching the connecting component 4 between a first state and a second state.

[0049] Specifically, the first hoop body 1 and the second hoop body 2 are semicircular ring structures, thereby forming a circular embracing space between the first hoop body 1 and the second hoop body 2 to support the elastic body.

[0050] In some embodiments, the mounting parts 3 are provided at both ends of the first hoop body 1, and two folding wings are provided, which are respectively installed on the mounting parts 3; in other embodiments, the mounting parts 3 can also be provided at both ends of the second hoop body 2;

[0051] It needs to be further explained that, in the actual operation process, the elastic body needs to be clamped in the embracing space formed by the first hoop body 1 and the second hoop body 2, the first hoop body 1 is relatively arranged above the second hoop body 2, the elastic body and the second hoop body 2 are fixed together by fasteners, adhesives, etc., and the action of the driving component is controlled to lock the first hoop body 1 and the second hoop body 2.

[0052] When it is necessary to launch the projectile, the combined structure of the projectile, the folding wings and the folding wing unlocking device is launched as a whole; during the flight, the combined structure can control the folding wings to unfold so that the folding wings assist the projectile in flying; when the folding wings and the projectile need to be separated from each other, the driving assembly is controlled to switch to the second state, so that the first hoop body 1 and the second hoop body 2 are unlocked, thereby completing the separation of the folding wings from the projectile.

[0053] The installation, locking and unlocking process of the above structure is relatively simple, and there is no need to reserve installation space for gas cylinders and pipelines. The locking and unlocking of the projectile body and the folding wings are achieved by switching the mechanical structure state, thereby improving the reliability of the device.

[0054] In some embodiments, two connecting assemblies 4 are provided, and are respectively disposed between the first end of the first hoop body 1 and the first end of the second hoop body 2 and between the second end of the first hoop body 1 and the second end of the second hoop body 2 .

[0055] When the two connecting components 4 are in the second state, the two ends of the first hoop body 1 lose connection with the two ends of the second hoop body 2, that is, separation is achieved.

[0056] In some embodiments, the connection component 4 includes:

[0057] A locking body 41, wherein the locking body 41 is mounted on the end of the first hoop body 1, and an insertion groove 42 is formed on the locking body 41, and the end of the second hoop body 2 can be inserted into the insertion groove 42;

[0058] A wedge-shaped stopper 43, wherein the wedge-shaped stopper 43 is rotatably mounted in the insertion groove 42, and a clamping groove 22 is provided at the end of the second hoop body 2 corresponding to the wedge-shaped stopper 43;

[0059] When the connecting assembly 4 is in the first state, the wedge-shaped stopper 43 rotates into the clamping groove 22 to lock the first hoop body 1 and the second hoop body 2. Figure 1 and Figure 2 When the connecting assembly 4 is in the second state, the wedge-shaped stopper 43 moves in a direction away from the snap-fit ​​groove 22 to separate the first hoop body 1 and the second hoop body 2, as shown Figure 3 and Figure 4 shown.

[0060] Specifically, the locking body 41 and both ends of the first hoop body 1 may be an integrated structure or a split structure.

[0061] Specifically, the driving assembly is connected to the wedge-shaped stopper 43 to drive the wedge-shaped stopper 43 to rotate.

[0062] During installation, the end of the second hoop body 2 is inserted into the insertion groove 42 on the locking body 41, and the driving component drives the wedge-shaped stopper 43 to move, so that the wedge-shaped stopper 43 rotates into the clamping groove 22, thereby realizing the locking between the second hoop body 2 and the first hoop body 1; when unlocking is required, the driving component drives the wedge-shaped stopper 43 to move in the opposite direction, so that the wedge-shaped stopper 43 moves in the opposite direction away from the clamping groove 22, thereby realizing the unlocking between the second hoop body 2 and the first hoop body 1.

[0063] In some embodiments, the insertion groove 42 is arranged on the side of the locking body 41 close to each other; a first inclined surface 44 is arranged in the insertion groove 42 and close to the second hoop body 2; along the direction away from the center line of the clamp assembly, the distance from the first inclined surface 44 to the side of the insertion groove 42 away from the second hoop body 2 gradually decreases;

[0064] The first inclined surface 44 is provided with a mounting groove 45, and the wedge-shaped stopper 43 is rotatably mounted in the mounting groove 45 along a second direction, wherein the second direction is parallel to the center line of the clamp assembly;

[0065] A second inclined surface 21 is disposed at the end of the second hoop body 2 corresponding to the first inclined surface 44 , and the engaging groove 22 is disposed on the second inclined surface 21 .

[0066] Specifically, the locking body 41 is installed at both ends of the first hoop body 1, and the insertion groove 42 is installed on the side of the locking body 41 close to each other;

[0067] Since a first inclined surface 44 is provided in the insertion groove 42 and a second inclined surface 21 is provided at the end of the second hoop body 2 corresponding to the first inclined surface 44, in the unlocked state (i.e., the second state), relative movement between the second inclined surface 21 at the end of the second hoop body 2 and the first inclined surface 44 of the first hoop body 1 is facilitated, thereby facilitating disengagement.

[0068] In some embodiments, the first hoop body 1 includes a first sub-hoop body 11 and a second sub-hoop body 12 arranged at both ends of the first sub-hoop body 11; the first sub-hoop body 11 and the second sub-hoop body 12 are hinged along a first hinge axis; the first hinge axis is parallel to the center line of the clamp assembly.

[0069] Specifically, the locking body 41 is installed at the end of the second sub-hoop body 12; in the above structure, the second sub-hoop body 12 can rotate along the hinge axis, so when the connecting component 4 is in the unlocked state (ie, the second state), it is convenient for the second inclined surface 21 and the first inclined surface 44 to disengage from each other.

[0070] Furthermore, the first inclined surface 44 is an arc-shaped inclined surface, and the normal direction of the first inclined surface 44 intersects with the first hinge axis, so that the second sub-hoop body 12 can rotate along the first hinge axis and ensure that the separation can slide along the mechanical path to achieve mutual separation from the first hoop body 1.

[0071] Furthermore, graphite powder is coated between the first inclined surface 44 and the second inclined surface 21 to prevent adhesion or jamming between the two.

[0072] In some embodiments, an elastic member 46 is provided between the insertion groove 42 on a side away from the wedge-shaped stopper 43 and the end of the second hoop body 2 .

[0073] Furthermore, the elastic member 46 is a circular compression spring; when the connecting component 4 is in the first state, the elastic member 46 is in a compressed state; when the connecting component 4 is switched to the second state, the first hoop body 1 and the second hoop body 2 are unlocked, and at this time, under the elastic force of the elastic member 46, the first hoop body 1 and the second hoop body 2 are separated from each other; therefore, by setting the elastic member 46, a separation pushing force is provided, which is conducive to rapid separation.

[0074] In some embodiments, a spring pressure plate 47 is provided between the mounting groove 45 and the wedge-shaped stopper 43 , and the spring pressure plate 47 is used to provide a pre-tightening force to the wedge-shaped stopper 43 in a direction pointing to the clamping groove 22 .

[0075] Specifically, the spring pressure plate 47 is distributed in an S shape as a whole, and the bottom is a mounting flange surface. The mounting flange surface is provided with a mounting hole for fixing to the bottom of the mounting groove 45.

[0076] The spring pressure plate 47 is provided to provide a pre-tightening force for the wedge-shaped stopper 43 to prevent the wedge-shaped stopper 43 from vibrating off during the vibration process.

[0077] In some embodiments, the drive assembly comprises:

[0078] A rotating shaft 5, wherein the rotating shaft 5 is rotatably mounted in the inserting groove 42, and the wedge-shaped stopper 43 is fixedly mounted on the rotating shaft 5;

[0079] A driving motor 6, wherein an output end of the driving motor 6 is connected to the rotating shaft 5 through a gear set, and is used for driving the rotating shaft 5 to rotate along its axis.

[0080] Furthermore, the gear set includes a driving gear 7 and a driven gear 8 meshing with each other; the driving gear 7 is mounted on the driving motor 6, and the driven gear 8 is mounted on the rotating shaft 5;

[0081] Furthermore, the driving gear 7 and the driving motor 6 can be designed as an integrated structure to reduce the installation space and improve the transmission accuracy and structural strength;

[0082] Furthermore, the driven gear 8 and the rotating shaft 5 are an integrated structure, and the driven gear 8 is a standard spur gear, and the hardness of the tooth surface after quenching and tempering is RHC25-32; combining the driven gear 8 with the rotating shaft 5 can improve the structural strength and reduce the transmission error caused by the clearance fit;

[0083] Furthermore, the rotating shaft 5 is a stepped shaft, which can be circumferentially limited and installed with bearings; the rotating shaft 5 is rotatably installed in the insertion groove 42 by installing bearings 49 .

[0084] Furthermore, the wedge-shaped stopper 43 is fixed to the rotating shaft 5 via a flat key 48 .

[0085] In some embodiments, the folding-wing unlocking device further includes: a control unit; the control unit is configured to receive control instructions and control the action of the driving component to switch the first state and the second state of the connecting component.

[0086] Specifically, the control unit may receive the information in a wireless manner. For example, when the control unit receives a first control instruction, the control unit controls the driving component to operate, and the driving component drives the connecting component to switch to the first state; when the control unit receives a second control instruction, the control unit controls the driving component to operate, and the driving component drives the connecting component to switch to the second state.
