Description

Technical Field

[0001] This invention relates to the field of rocket separation connectors, and in particular to a connection unlocking device for launch vehicle separation. Background Technology

[0002] In order to transport a satellite to its designated orbit, a launch vehicle needs to jettison the lower stage that has completed its mission during flight. At present, two-stage launch vehicles are the main type used. That is, the entire mission profile will include interstage separation (jeopardizing a substage) and satellite-rocket separation (satellite entering the designated orbit). Both separations are achieved through a connection unlocking device.

[0003] Most existing launch vehicle connection and unlocking devices employ explosive bolts or explosive cutting cables. Explosive bolts are point-type separation and unlocking structures, while explosive cutting cables are line-type separation and unlocking devices. Explosive bolts contain explosives and are machined with a fracture section. Connection is achieved by the explosive bolt and nut, linking the upper and lower stages of the launch vehicle. Unlocking is achieved by detonating the explosive to sever the fracture section of the explosive bolt. Explosive cutting cables connect the upper and lower stages of the launch vehicle via upper and lower supports. Unlocking is achieved by detonating the explosive, causing the gasbag tube to expand instantaneously and cut the rivets between the upper and lower supports.

[0004] Both of these devices generate high-energy shock waves upon detonation, causing significant impact on nearby equipment. Cut bolt ends and rivets may scatter, potentially damaging nearby equipment or structures. Furthermore, the separation process releases explosive contaminants, polluting the surrounding environment. Both explosive bolts and explosive cutting cords are pyrotechnics with high risks, requiring substantial manpower and resources for safe production, storage, transportation, and use. The number of qualified manufacturers is limited, and production cycles are long. Summary of the Invention

This allows the upper and lower stages of the launch vehicle to be unlocked during stage separation, while avoiding the effects of shock waves and contaminants. Attached Figure Description

[0017] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figure 1 As shown, an embodiment of the present invention provides a connection unlocking device for separation of a launch vehicle, comprising: Locking pin 11, which is fixedly connected to the upper stage 2 of the launch vehicle; Locking box 12 is fixedly connected to the lower stage 3 of the launch vehicle; The locking pin 11 is inserted into the cavity of the locking box 12 and engages with the sliding component inside the locking box 12 to fix the upper stage 2 of the launch vehicle to the lower stage 3 of the launch vehicle. When the upper stage 2 of the launch vehicle separates from the lower stage 3 of the launch vehicle, the sliding component inside the locking box 12 moves, causing the locking pin 11 to disengage from the sliding component, thereby disengaging the locking pin 11 from the locking box 12.

[0019] In this embodiment, the connection unlocking device includes a locking pin 11 and a locking box 12, such as Figure 2 As shown, the locking pin 11 is fixedly connected to the upper stage 2 of the launch vehicle via multiple first connecting pieces 111. Figure 3 As shown, the locking box 12 is fixedly connected to the lower stage 3 of the launch vehicle via multiple second connectors 1211. During launch vehicle flight, the locking pin 11 is inserted into the cavity of the locking box 12, and under the constraint of the sliding assembly within the locking box 12, the locking pin 11 engages with the locking box 12. This fixes the upper stage 2 and lower stage 3 of the launch vehicle together. When the lower stage 3 completes its mission and needs to be jettisoned, the sliding assembly within the locking box 12 moves, causing the locking pin 11 to disengage. When the lower stage 3 moves, it drives the locking pin 11 fixed thereto to move, and the locking pin 11 is pulled out of the locking box 12, completing the interstage separation of the launch vehicle. It should be noted that in this invention, multiple connection unlocking devices are provided for launch vehicle separation, and the number of connection unlocking devices used on the separation surface is determined according to the diameter and load of the launch vehicle body. The number of connection unlocking devices is commonly 8, 10, 12, 14, 16, 18, 20, etc., and the number is mostly even, and they are evenly distributed around the perimeter of the arrow body.

[0020] In an optional embodiment of the present invention, the bottom of the locking pin 11 is provided with a communicating square hole 112, the top of the square hole 112 is a horizontal plane, and the bottom of the square hole 112 consists of two opposing inclined planes, which gradually rise from the outer surface of the locking pin 11 to the center of the locking pin 11.

[0021] In this embodiment, as Figure 4 As shown, the upper part of the locking pin 11 is a flat plate structure with four through holes at the four corners for installing the first connector 111. The lower part is a cylindrical structure with a horizontal square hole 112 at the bottom. Figure 5 The diagram shows a cross-sectional view of the square hole 112. Its bottom has a sloping structure from the outside to the inside, which can play a locking role.

[0022] In an optional embodiment of the present invention, the locking box 12 includes: The box body 121 is fixedly connected to the lower stage 3 of the launch vehicle via a plurality of second connectors 1211; The cover 122 is fixedly connected to the box body 121 by a plurality of fasteners 123; The first sliding assembly and the second sliding assembly are disposed in the cavity enclosed by the box body 121 and the box cover 122. The first sliding assembly and the second sliding assembly have the same structure. When the upper stage 2 and the lower stage 3 of the launch vehicle are fixedly connected, the first sliding assembly and the second sliding assembly are engaged with the locking pin 11. An actuator 129 is disposed between the first sliding component and the second sliding component for driving the movement of the first sliding component and the second sliding component.

[0023] like Figure 6 As shown, the locking box 12 is formed by a box body 121 and a box cover 122, and the box body 121 and the box cover 122 are fixedly connected by four fasteners 123. Figure 7 As shown, a first sliding assembly and a second sliding assembly are disposed within the cavity of the housing 121, and an actuator 129 is located between the first sliding assembly and the second sliding assembly. The first sliding assembly and the second sliding assembly are mirror images of each other.

[0024] like Figure 7 As shown, in an optional embodiment of the present invention, the first sliding component or the second sliding component includes: The upper guide member 124 is fixedly connected to the box body 121, and the upper guide member 124 has a square through hole in the middle; for example Figure 8 As shown, the upper guide member 124 is a square column structure with a square through hole in the middle for guiding the square wedge head 1261 of the sliding member 126. Both ends are rounded square protrusions that can be inserted into the corresponding shaped holes on the upper part of the box body 121 and the box cover 122 respectively to achieve complete positioning.

[0025] The lower guide member 125 is fixedly connected to the box body 121, and the lower guide member 125 has a circular through hole in the middle; for example Figure 9 As shown, the lower guide member 125 is a plate structure with a round hole in the middle for guiding the inner end of the lower guide shaft 1264 of the sliding member 126. Both ends are waist-shaped hole protrusions that can be inserted into the matching shaped holes on the upper part of the box body 121 and the box cover 122 respectively to achieve complete positioning.

[0026] Guide sliding members 126, with their upper and lower ends passing through the square through holes of the upper guide member 124 and the circular through holes of the lower guide member 125 respectively. For example... Figure 10 As shown, the guide sliding member 126 includes: Connector 1262; the connector 1262 is vertically arranged and is used to connect the other parts of the guide sliding member 126. A square wedge head 1261 is fixedly connected to the first end of the connecting body 1262; the square wedge head 1261 passes through the square through hole of the upper guide member 124 and is inserted into the square hole 112 of the locking pin 11 to fix the locking pin 11.

[0027] A lower guide shaft 1264 is fixedly connected to the second end of the connecting body 1262; the two ends of the lower guide shaft 1264 pass through the round hole of the lower guide member 125 and the side wall opening of the box body 121 respectively, and the lower guide shaft 1264 is fixed by the lower guide member 125 and the box body 121.

[0028] An auxiliary unlocking pin 1263 is fixedly connected to the middle of the connecting body 1262; the square wedge head 1261, the lower guide shaft 1264, and the auxiliary unlocking pin 1263 are arranged parallel to each other.

[0029] In an optional embodiment of the present invention, the first end of the square wedge 1261 passes through the square through hole of the upper guide member 124 and is inserted into the square hole 112 of the locking pin 11. The lower surface of the first end of the square wedge 1261 is an inclined surface, and the inclination angle of the inclined surface is the same as the inclination angle of the two opposite inclined planes of the square hole 112 of the locking pin 11. When the upper stage 2 and the lower stage 3 of the launch vehicle are fixedly connected, the square wedges 1261 of the two opposite sliding members 126 in the first sliding assembly and the second sliding assembly are respectively inserted into the square hole 112 of the locking pin 11. Since the bottom surface of the square hole 112 is composed of two inclined surfaces, the first ends of the two square wedges 1261 are respectively inserted into the square hole 112 and match the inclined surface of the square hole 112. The inclined surface makes the locking pin 11 fixed in the horizontal direction and unable to move horizontally.

[0030] The second end of the square wedge head 1261 is fixedly connected to the compression spring 128, and the compression spring 128 is fixedly connected to the box body 121 through the positioning pin 127; under the pressure of the compression spring 128, the two guide sliding parts 126 can maintain the minimum distance between each other in their natural state.

[0031] The first end of the lower guide shaft 1264 passes through the circular through hole of the lower guide member 125, and the second end of the lower guide shaft 1264 passes through the lower hole of the box body 121 and is slidably connected to the box body 121. The auxiliary unlocking pin 1263 passes through the central hole of the housing 121 and is slidably connected to the housing 121. The auxiliary unlocking pin 1263 is exposed through the central hole in the side wall of the housing 121, and has a small hole at the top. In an emergency, the auxiliary unlocking pin 1263 can be pulled directly from the outside of the housing 121, causing the guide slide 126 to move horizontally, thereby releasing the locking pin and unlocking in an emergency.

[0032] like Figure 11 As shown, the upper part of the box 121 has a round hole in the middle for the locking pin 11 to pass through. There are four through holes at the four corners for installing the second connector 1211. There are three holes on each side. The upper hole is for installing the positioning pin 127. The middle hole is for passing through the auxiliary unlocking pin 1263 of the sliding member 126. The lower hole is for passing through the outer end of the lower guide shaft 1264 of the sliding member 126. There is a stepped groove for installing the box cover 122 at the front. There are five openings at the rear. The long waist hole in the center is for the control pipeline of the actuator 129 to pass through. The two holes at the top are for positioning the upper guide member 124. The two holes at the bottom are for positioning the lower guide member 125.

[0033] like Figure 12 As shown, the cover 122 is a flat plate with four through holes at its four corners for mounting fasteners 123, two holes at the top for positioning the upper guide 124, and two holes at the bottom for positioning the lower guide 125.

[0034] like Figure 13 As shown, in an optional embodiment of the present invention, the actuator 129 includes: A cylindrical actuator body 1291; the bottom of the actuator body 1291 is provided with an unlocking power inlet hole 12911, and the bottom of the side wall of the actuator body 1291 is provided with a locking power inlet hole 12912; Two actuator pistons 1292 are located inside the actuator body 1291, and the actuator pistons 1292 extend outside the actuator body 1291. The actuator pistons 1292 are fixedly connected to the connecting body 1262.

[0035] In this embodiment, the actuator 129 includes an actuator body 1291 and two actuator pistons 1292. The actuator body has an unlocking power inlet hole 12911 in the center and locking power inlets 12912 on both sides. The outer ends of the actuator pistons 1292 on both sides are fixedly connected to the connecting members 1262 in the two sliding members 126, respectively. The movement of the actuator pistons 1292 drives the sliding members 126 to move together.

[0036] When energy (high-pressure gas or liquid) enters the unlocking inlet 12911, the two actuator pistons 1292 move away from each other, causing the two sliding members 126 to move away from each other as well. The square wedge head 1261 moves out of the square hole 112 of the locking pin 11, thus unlocking the device. When energy (high-pressure gas or liquid) enters the locking inlet 12912, the two actuator pistons 1292 move towards each other, causing the two sliding members 126 to move towards each other as well. The square wedge head 1261 inserts into the square hole 112 of the locking pin 11 and is pressed by the ramp, thus locking the device.

[0037] In its natural state, due to the spring force of the compression spring 128, the two sliding parts 126 on the left and right sides approach each other to their minimum distance. At this time, the locking pin 11 is in a connected state in the locking box 12. When unlocking is required, energy can be supplied through the unlocking energy inlet hole 12911 or by pulling the two sliding parts 126 outwards through the small hole at the top of the auxiliary unlocking pin 1263, thereby moving the two sliding parts 126 away from each other to their maximum distance and unlocking them. At this time, the cylindrical head of the locking pin 11 can freely move in and out of the locking box 12. When locking is required, the two sliding parts 126 need to be at their maximum distance. The cylindrical head of the locking pin 11 is then placed into the locking box 12, and energy is supplied through the locking energy inlet hole 12912. The two sliding parts 126 approach each other to their minimum distance, and the energy is maintained. At this time, the upper stage and the lower stage of the rocket are tightly fitted, achieving a locked connection.

[0038] The embodiments of the present invention described above are completely free of pyrotechnics; the connection and unlocking of the device can be achieved simply by introducing energy through different ports. Separation does not generate any impact loads, contaminants, or debris splashing, and is completely hazardless, facilitating production and significantly shortening the production cycle.

[0039] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
