[0028] The utility model provides an electrical separation unlocking mechanism for passive trigger unlocking. Figure 1-Figure 5 This is a specific embodiment of an electrical separation unlocking mechanism for passively triggered unlocking provided by the utility model.

[0029] like Figure 1 , an embodiment of the utility model provides an electrical separation and unlocking mechanism 100 for passively triggered unlocking, comprising a housing 1, characterized in that the housing 1 is provided with a locking mechanism, a separation mechanism 5 and a socket electrical connector 4 for connecting to a projectile, the separation mechanism 5 comprising a separation bracket 51 and a separation power unit 52 for driving the separation bracket 51 to perform linear motion, the locking mechanism comprising a constraint locking member 2 mounted on the housing 1 and an unlocking actuator 3 that is locked with the constraint locking member 2, the socket electrical connector 4 is mounted on the unlocking actuator 3, the unlocking actuator 3 is movably connected to the separation bracket 51 and can move relative to the separation bracket 51 to release the constraint of the constraint locking member 2, and the action direction of the separation power unit 52 is parallel to the axial direction of the socket electrical connector 4.

[0030] In the present utility model, the separation mechanism 5 includes a separation bracket 51 and a separation power unit 52 for driving the separation bracket 51 to perform linear motion. The locking mechanism includes a constraint locking member 2 installed on the shell 1 and an unlocking actuator 3 that is locked with the constraint locking member 2. The socket electrical connector 4 is installed on the unlocking actuator 3. The unlocking actuator 3 is movably connected to the separation bracket 51 and can move relative to the separation bracket 51 to release the constraint of the constraint locking member 2. The action direction of the separation power unit 52 is parallel to the axial direction of the socket electrical connector 4. Before the missile is launched, the socket electrical connector 4 is in a connected state with the missile. When the missile is launched, the missile will drive the socket electrical connector 4 to move along the course. The movement of the socket electrical connector 4 drives the unlocking actuator 3 to move relative to the separation bracket 51 to release the constraint of the locking member 2. After the constraint is released, the separation power unit 52 drives the separation bracket 51 to move linearly in a direction parallel to the axis of the socket electrical connector 4, thereby driving the socket electrical connector 4 to pull out the missile to achieve electrical separation. This electrical separation method is based on the movement of the missile and then triggers the unlocking actuator 3 to move until the constraint is released. It is a passive triggering method and does not require active unlocking before launching, which greatly shortens the launch time of the missile. In addition, the passive triggering unlocking method has a simple structure and high reliability, and there will be no situation where the active triggering unlocking fails to successfully unlock, thereby causing the missile to fail to launch.

[0031] In addition, the structure has good versatility and the product structure has good environmental adaptability. It has undergone environmental tests such as vibration, impact, high temperature, low temperature, temperature shock, low temperature and low pressure, as well as live-fire test assessments. Socket electrical connectors 4 of different specifications can be selected and installed on the unlocking actuator 3, so that it can be used in a variety of projectiles and environments.

[0032] Specifically, in some embodiments, the unlocking actuator 3 includes an actuator rod 31, one end of which is hinged to the socket electrical connector 4, the middle of which is hinged to the separation bracket 51, and the other end of which is in contact with the restraining locking member 2. Figure 1 In the initial state before the projectile is launched, the length of the actuator rod 31 is parallel to the axial direction of the socket electrical connector 4. After the projectile is launched, the socket electrical connector 4 drives one end of the actuator rod 31 to move, causing the actuator rod 31 to rotate about the hinge axis hinged to the separation bracket 51, thereby driving the other end of the actuator rod 31 to move and release the restraining locking member 2, thereby achieving unlocking. In this way, passive triggering and restraint release are achieved simultaneously, greatly improving the efficiency of triggering and unlocking. Moreover, the entire unlocking process adopts a purely mechanical structure, which is simple in structure and highly reliable. It should be noted that the axial direction of the hinge axis at the hinged connection between the actuator rod 31, the socket electrical connector 4, and the separation bracket 51 is perpendicular to the axial direction of the socket electrical connector 4. Specifically, this axial direction is perpendicular to the plane formed between the top plate 11 and the bottom plate 12.

[0033] Specifically, in some embodiments, see Figure 5 Two actuator rods 31 are provided, and the two actuator rods 31 are arranged in parallel. A linkage rod 32 is provided on the socket electrical connector 4. The two actuator rods 31 are respectively hinged to the linkage rods 32 to form a parallelogram linkage mechanism. The constraint locking member 2 is provided in two matching configurations. This parallelogram mechanism improves the reliability of the unlocking process compared to using a single actuator rod 31 to trigger unlocking. It is also worth mentioning that under the action of this parallelogram linkage mechanism, the linkage rod 32 can always remain parallel to the separation bracket 51 during the movement of the socket electrical connector 4. Therefore, when the socket electrical connector 4 on the linkage rod 32 moves axially with the separation bracket 51 and separates from the projectile, the socket electrical connector 4 is removed in a direction parallel to its own axial direction and does not tilt. This helps to prevent damage to the socket electrical connector 4 and surrounding structures caused by lateral or torsional forces generated by tilting during the separation process.

[0034] Specifically, in some embodiments, the constraint locking member 2 includes a constraint shell 21 and a latch 23. The constraint shell 21 is mounted on the housing 1. The constraint shell 21 defines an avoidance groove 22. The latch 23 is movably arranged in the avoidance groove 22. One end of the actuator rod 31 abuts against the latch 23. Through this arrangement, the locking method of the actuator rod 31 abutting against the latch 23 has good reliability. Moreover, after the actuator rod 31 moves to release the constraint of the constraint locking member 2, it will continue to move along the action direction of the separation power unit 52 along with the separation bracket 51. Under the action of the avoidance groove 22, the latch 23 can be retracted into the avoidance groove 22 when it is pushed by the actuator rod 31, thereby reducing the interference of the latch 23 on the subsequent movement of the actuator rod 31 after the unlocking is completed.

[0035] Specifically, in some embodiments, the restraining locking member 2 further includes a return spring 24, and the return spring 24 is connected between the bottom of the avoidance groove 22 and the latch 23. The latch 23 at least partially protrudes from the avoidance groove 22. Through this arrangement, after completing the electrical separation of the projectile once, the latch 23 is pushed into the avoidance groove 22 during the movement of the actuator rod 31. When it is necessary to launch again, the actuator rod 31 can be operated to move back to the initial state before launching. In order to allow the latch 23 to abut and lock the actuator rod 31 again, the return spring 24 pushes the latch 23 to a locking position abutting against the actuator rod 31 to lock the actuator rod 31, thereby achieving multiple reuse of the passively triggered electrical separation unlocking mechanism 100, thereby improving practicality.

[0036] Specifically, in some embodiments, a contact slope 231 is formed on the end of the latch 23 away from the bottom of the avoidance groove 22 and away from the actuator rod 31. Figure 3 When the electrical separation unlocking mechanism 100 that has completed the passive trigger unlocking of electrical separation needs to be locked again, it is necessary to operate the actuator rod 31 to reset to the initial state before firing, which is equivalent to moving vertically downward as shown in the figure. At this time, the latch 23 will interfere with the movement of the actuator rod 31. By setting the end face that abuts the actuator rod 31 into an inclined surface, the actuator rod 31 can move more smoothly when it is subjected to the force of the latch 23, reducing interference and thus improving the locking efficiency.

[0037] Specifically, in some embodiments, the end surface of the actuator rod 31 that contacts the latch 23 is an arcuate surface. This arrangement allows the actuator rod 31 to smoothly contact the latch 23 during the unlocking rotation process. The smooth contact of the arcuate surface reduces friction and collision between the actuator rod 31 and the latch 23, thereby improving the wear resistance between the actuator rod 31 and the latch 23 and extending the service life of the passively triggered electrical release mechanism 100. Furthermore, because the smooth contact of the arcuate surface reduces friction and resistance, the actuator rod 31 can more quickly release the restraining locking member 2 during rotation, thereby increasing the release speed. This design can further reduce the time required for firing.

[0038] Specifically, in some embodiments, the separation power unit 52 includes a separation spring 521, which is disposed between the separation bracket 51 and the housing 1. The axial direction of the separation spring 521 is parallel to the axial direction of the receptacle electrical connector 4. It is understood that when the unlocking actuator 3 is locked with the restraining locking member 2, the separation spring 521 is in a compressed state. Therefore, after the restraint of the restraining locking member 2 is released, the separation spring 521 drives the unlocking actuator 3 to move, causing the receptacle electrical connector 44 to separate from the projectile.

[0039] Specifically, in some embodiments, the shell 1 includes a top plate 11 and a bottom plate 12, the top plate 11 and the bottom plate 12 are arranged relative to each other, the separation bracket 51 is movably arranged between the top plate 11 and the bottom plate 12, and the separation spring 521 is arranged between the separation plate and the bottom plate 12.

[0040] Specifically, in some embodiments, the housing 1 is provided with a guide structure for movably guiding the separation bracket 51. The guide structure includes a guide post 13 provided between the top plate 11 and the bottom plate 12. The axial direction of the guide post 13 is parallel to the axial direction of the receptacle electrical connector 4. The separation bracket 51 is movably mounted on the guide post 13 via a guide sleeve. The separation spring 521 is mounted on the guide post 13 and is located between the separation plate and the bottom plate 12.

[0041] The present invention further provides a launching device, comprising a launching shell, in which the above-mentioned passively triggered unlocking electrical separation unlocking mechanism 100 is installed, wherein the socket electrical connector 4 is suitable for pluggable connection with the launched object.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
