Description

Technical Field

[0001] This utility model belongs to the field of aerospace technology and relates to a spacecraft suitable for space travel; in particular, it relates to a forced disconnection device for a spacecraft used in space travel, especially a forced disconnection device for electrical connectors used in pre-launch spacecraft. Background Technology

[0002] During launch from the test range, the launch vehicle typically has multiple electrical connectors located in the mid-fuselage section. These connectors belong to the telemetry, tracking, and command (TT&C) subsystem and the power distribution subsystem, respectively transmitting liquid level signals and supplying power to the launch vehicle from the ground. The electrical connectors cannot detach automatically before launch; a forced detachment mechanism must be installed on the ground launch equipment (swing arm) to forcibly pull the connectors away from the launch vehicle. After successful detachment, a signal must be sent back to the power control console to confirm whether the detachment was successful.

[0003] A forced detachment mechanism is a mechanism that uses mechanical movement to forcibly pull the electrical connector away from the carrier before firing, and can also retrieve the connector to prevent it from hitting the carrier and damaging the thermal protection structure if it falls off. During operation, the movement distance of the forced detachment mechanism needs to be precisely adjusted to prevent the connector from failing to detach or the controller from failing to detect the detachment status after it has detached.

[0004] Currently, launch vehicles typically use a hydraulic system at the test range. This system uses a drive pump and oil source to move a piston, which then detaches the electrical connector from the launch vehicle. This method is bulky and complex, and has low precision. It is suitable for traditional launch vehicles with launch towers and large lever systems, where the lever's swing direction is the same as the connector's detachment direction. It is not suitable for winged reusable launch vehicles with simple lever systems or for situations where the connector's detachment direction is inconsistent with the lever's swing direction.

[0005] To solve the above-mentioned technical problems, the prior art has proposed a strong disconnection device that uses a motor to drive the electrical connector to disconnect. The solution uses a slider to transfer the pull rope to achieve the effect of turning and pulling the electrical connector.

[0006] However, the existing forced release device requires the installation of a motor assembly to wind the pull rope and then pull the slider. How to fix the motor assembly to the forced release device has become a problem that needs to be solved. At the same time, how to set the motor assembly to effectively wind or release the pull rope that changes the direction of the pull has become an urgent technical problem to be solved.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

The mounting portion includes a horizontal portion that extends horizontally outward from the lower end of the lower bent portion. The lower end surface of the horizontal portion is in contact with the upper end surface of the mounting plate and is fixedly connected to the mounting plate by screws that pass through from top to bottom.

[0018] Furthermore, the upper side wall of the winding reel has a through hole that runs vertically through the winding reel; the pull rope is circumferentially wound in the winding reel, and one end of the pull rope passes through the through hole and exits the winding reel. The end of the pull rope that passes through the winding reel is connected to the puller. The outer circumference of the puller is larger than the diameter of the through hole to keep the end of the puller fixedly connected to the winding reel and rotate synchronously around the axis.

[0019] Furthermore, a downwardly protruding mounting rib is provided below the cover, and a horizontal mounting part is provided at the lower end of the mounting rib; at least part of the horizontal mounting part is located above the axis of the winding reel, and screws pass through the horizontal mounting part and the central axis of the winding reel from top to bottom, and are coaxially threaded and fixed with the upper end of the motor shaft, so as to form a fixed installation between the winding reel and the cover that can rotate around the axis.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figures 1 to 6 As shown, this embodiment provides a forced disconnection device for a spacecraft electrical connector, comprising: a housing 100, installed on the upper side of a swing arm 1 on a spacecraft launch pad; the housing 100 is composed of a mounting plate 101 and a cover 102, the mounting plate 101 being fixedly installed on the upper side of the swing arm 1, and the cover 102 being correspondingly fastened to the mounting plate 101, together forming a mounting cavity 103, and each forced disconnection component of the forced disconnection device being installed in the mounting cavity 103; the mounting cavity 103 includes a strip-shaped main mounting cavity 1031 extending along the axial direction and in the front-rear orientation of the swing arm 1, and a slider guide rail assembly 500 extending along the axial direction is installed in the main mounting cavity 1031; the first end of the main mounting cavity 1031 is provided with a guide rail towards the swing arm 1. Each of the two protruding drive unit mounting cavities 1032 houses a motor assembly 400, which is wound around one end of a pull rope 700 to pull the pull rope 700 and thus pull the slider 501 of the slider guide assembly 500. The opposite second end has a reversing wheel assembly mounting cavity 1033, which houses a reversing wheel assembly 900 to change the direction of the pull rope 700 from front-to-back to left or right. The left or right side wall of the reversing wheel assembly mounting cavity 1033 has a clamping assembly 600 through which the pull rope 700 passes, and the end of the pull rope 700 is connected to the electrical connector 2. Furthermore, to facilitate the storage of the pull rope connected to the disconnected electrical connector 2, a storage box assembly 800 is provided on the outer side wall of the clamping assembly 600.

[0039] With the above configuration, each component of the forced disengagement device is installed in a separate chamber inside the housing, effectively ensuring that the operation of each component of the forced disengagement device is not affected by external interference. At the same time, by setting the housing into two parts, the forced disengagement components can be pre-assembled onto the mounting plate. The mounting plate is then installed on the swing arm of the launch platform before the housing is assembled, which is a significant technological advancement that greatly improves the installation convenience and stability of the forced disengagement device.

[0040] Meanwhile, in order to detect and determine whether the movement of the forced release component inside the housing 100 of the forced release device is in place, the mounting cavity 103 also includes outwardly protruding limit switch mounting cavities 1034 respectively provided in the middle and on the left and right sides of the main mounting cavity 1031. Each limit switch mounting cavity 1034 is equipped with a limit switch assembly 200 for detecting the position of the slider 501. Preferably, at least two sets of limit switch mounting cavities 1034 are provided at different front and rear positions of the main mounting cavity 1031. Each set of limit switch mounting cavities 1034 includes one limit switch mounting cavity 1034 respectively provided on the left and right sides of the main mounting cavity 1031, and the left and right limit switch mounting cavities 1034 of each set are symmetrically arranged, so as to use two sets of limit switch assemblies 200 to detect and determine the same position, thereby improving the accuracy of the determination. Each limit switch assembly 200 includes two limit switches 201 that are symmetrical about the left and right sides of the guide rail 502. Each limit switch 201 includes a rocker arm 202 that extends in the direction of the guide rail 502. The end of the rocker arm forms a contact 203. When the slider 501 moves to the corresponding position, it contacts the contact 203 and pushes the rocker arm to swing to generate a trigger signal.

[0041] In this embodiment, the first end of the main mounting cavity 1031 is provided with drive unit mounting cavities 1032 that protrude to the opposite sides of the swing arm. A motor assembly 400 is installed in each of the two drive unit mounting cavities 1032. The motor assembly 400 includes a motor 401 located below the mounting plate 101 and outside the mounting cavity 103, and a winding wheel 402 located above the mounting plate 101 and inside the mounting cavity. The motor shaft 403 passes through the mounting plate 101 from bottom to top and is coaxially connected to the winding wheel 402, which is used to fix the motor assembly 400 on the mounting plate 101.

[0042] In this embodiment, the mounting plate 101 is provided with a through mounting hole 404. The motor shaft 403 coaxially passes through the mounting hole 404 and enters the mounting cavity 103. The radial dimension of the outer periphery of the motor 401 is larger than the radial dimension of the mounting hole 404, and it is fixedly mounted on the lower side of the mounting plate 101 by screws. The radial dimension of the outer periphery of the winding reel 402 is larger than the radial dimension of the mounting hole 404, and it is located in the mounting cavity 103 with a gap between it and the mounting plate 101.

[0043] In this embodiment, the upper end face of the motor 401 is provided with a ring-shaped positioning rib 405. The ring-shaped positioning rib 405 extends into the mounting hole 404, and the outer peripheral wall of the ring-shaped positioning rib 405 is in corresponding contact with the inner peripheral wall of the mounting hole 404. The height of the ring-shaped positioning rib 405 is lower than the depth of the mounting hole 404, so that the upper end of the ring-shaped positioning rib 405 is lower than the top surface height of the mounting plate 101. The lower side of the mounting plate 101 is provided with a ring of downwardly protruding lower mounting ribs 406. The lower mounting ribs 406 are located on the outer periphery of the outer peripheral side wall of the motor 401. The upper part of the motor 401 is coaxially inserted into the lower mounting ribs 406, and a gap is maintained between the outer peripheral side wall of the motor 401 and the lower mounting ribs 406.

[0044] In this embodiment, the motor 401 includes a motor mounting portion 407 located on the upper side. The motor mounting portion 407 is a block structure with a flat upper side, and mounting holes are provided at the four corners of the upper side of the block structure. A screw that penetrates the mounting plate from top to bottom is connected to the four corners of the motor mounting portion 407 that protrude from the mounting holes, so as to fix the motor 401 to the mounting plate 101. An annular positioning rib 405 is provided on the upper end face of the motor mounting portion 407; preferably, the annular positioning rib 405 is integrally provided with the motor mounting portion 407.

[0045] In this embodiment, the reel 402 is a horizontally extending wheel with a vertically arranged axis. The outer periphery of the wheel is provided with a groove 408 for the pull rope to be wound around. The radial cross section of the groove 408 is a cone shape that gradually narrows from the outer periphery to the center and rises at the top and bottom, so as to facilitate the storage of the pull rope 700. The lower center of the reel 402 is provided with a mounting groove with an open bottom and a closed top, into which the motor shaft 403 is inserted coaxially from bottom to top. The screw is inserted coaxially from top to bottom from the upper center of the reel 402 and is coaxially connected to the motor shaft 403 to fix the reel 402 on the motor shaft 403, so that the reel 403 and the motor shaft 403 rotate synchronously around the axis.

[0046] In this embodiment, a limiting bracket 409 for guiding the direction of the pull rope 700 is provided on the outer periphery of the winding reel 402; the limiting bracket 409 includes a vertically extending limiting rod 4090, the lower end of the limiting rod 4090 is fixedly connected to the mounting plate 101, and / or the upper end of the limiting rod 4090 is fixedly connected to the cover 102, and the limiting rod 4090 is located at any vertical position on the outer periphery of the winding reel 402, for guiding the winding pull rope 700 to change direction.

[0047] In this embodiment, the upper end of the limiting rod 4090 is provided with an upper bent portion 4091 that bends radially toward the center of the winding wheel 402. The upper bent portion 4091 is located on the upper side of the winding wheel 402 and is spaced apart from the upper sidewall of the winding wheel 402. The lower end of the limiting rod 4090 is provided with a lower bent portion 4092 that bends radially toward the center of the winding wheel 402. The lower bent portion 4092 is located on the lower side of the winding wheel 402 and is spaced apart from the lower sidewall of the winding wheel 402. The inner circumferential end of the lower bent portion 4092 bends downward and extends to the mounting plate 101 to form a mounting portion 4093. The mounting portion 4093 is in contact with the upper sidewall of the mounting plate 101 and is fixedly connected by bolts. The mounting portion 4093 includes a horizontal portion that extends horizontally outward from the lower end of the lower bent portion. The lower end surface of the horizontal portion is in contact with the upper end surface of the mounting plate 101 and is fixedly connected to the mounting plate 101 by screws that pass through from top to bottom.

[0048] In this embodiment, the upper side wall of the groove 408 of the winding reel 402 is provided with a through hole 4010 that runs vertically through the winding reel; the pull rope 700 is circumferentially wound in the groove 408 of the winding reel 402, and one end of the pull rope 700 passes through the through hole 4010 and exits the groove 408. The end of the pull rope 700 that exits the groove 408 is fixedly connected to the puller. The outer circumferential contour of the puller is larger than the diameter of the through hole 4010 so as to keep the end of the pull rope connected to the puller fixedly connected to the winding reel 402 and rotate synchronously around the axis.

[0049] In this embodiment, the following configuration can also be made: a mounting rib extending downward is provided below the cover 102, and a horizontal mounting part is provided at the lower end of the mounting rib; at least part of the horizontal mounting part is located above the axis of the winding reel 402, and screws pass through the horizontal mounting part and the central axis of the winding reel 402 from top to bottom, and are coaxially threaded and fixed with the upper end of the motor shaft 403, so as to form a fixed installation between the winding reel 402 and the cover 102 that can rotate around the axis, so that the two parts of the motor and the housing 100 are fixedly connected respectively, thereby improving the assembly stability of the motor assembly 400 and improving the overall integrity of the forced release device.

[0050] In this embodiment, the lower part of the motor 401 is provided with a control unit 4011, and the control unit 4011 is provided with a plurality of control buttons 4012 for controlling the motor 401 to work or stop, thereby controlling the motor shaft 403 to rotate forward, reverse, or stop around the shaft, so as to achieve the purpose of winding or releasing the pull rope.

[0051] In this embodiment, the lower side of the mounting plate 101 is provided with downwardly protruding left and right limiting ribs 104. The left and right limiting ribs 104 are arranged along the extension direction of the swing rod, and are located on the left and right sides of the swing rod 1, respectively. The left and right limiting ribs 104 are respectively limited and fitted with the corresponding side wall of the swing rod 1, which is used for horizontal pre-positioning when the mounting plate 101 is assembled above the swing rod 1. By providing limiting ribs 104 on the left and right sides of the mounting plate 101 that are fitted with the corresponding side wall of the swing rod 1, the mounting plate 101 is limited in the left and right directions. When the mounting plate 101 is assembled to the upper side of the swing rod 1, the limiting ribs 104 on both sides can be used to make the mounting plate 101 first be fastened to the swing rod 1, and then slide along the axial direction of the swing rod 1 to the installation position before screw fastening. This greatly improves the assembly convenience of the mounting plate 101.

[0052] In this embodiment, the mounting plate 101 is a strip-shaped plate that is flush with and adheres to the top surface of the swing arm 1. The left and right sides of the strip-shaped plate are respectively provided with downwardly bent and vertically extended folded edges, which respectively form left and right limiting ribs 104. The distance between the left and right limiting ribs 104 is equal to the width of the swing arm 1 in the left-right direction, used to ensure that the opposite sides of the left and right limiting ribs 104 are respectively in contact with the left and right side walls of the swing arm 1. The height of the left and right limiting ribs 104 is less than the vertical height of the swing arm 1. Simultaneously, the left and right limiting ribs 104 and the mounting plate 101 are integrated to reduce the number of mounting components. Furthermore, preferably, the mounting plate 101 is flush with the left and right widths of the swing arm 1 to ensure that the mounting plate 101 does not protrude from the swing arm 1, preventing other components from being attached to the swing arm 1 or scratched during the movement of the swing arm 1.

[0053] In this embodiment, the main mounting cavity 1031 has a limit switch mounting cavity 1034 protruding to the left and right sides in the middle. The limit switch mounting cavity 1034 is connected to the main mounting cavity 1031 so that the contacts of the switch assembly 200 installed in the limit switch mounting cavity 1034 can extend into the main mounting cavity 1031 to contact the slider 501 and move to generate a switch signal. The outer periphery of the protruding part of the mounting plate 101 corresponding to the lower side of the limit switch mounting cavity 1034 is provided with a second limiting rib 1041. The protruding part of the mounting plate 101 is located on both sides of the rocker arm 1 in the front and rear directions. Each is provided with a second limiting rib 1041 that extends vertically outward; the first end of each second limiting rib 1041 is located near the mounting plate and is bent and connected to the vertical rib 104, and is in contact with the outer wall of the corresponding side of the swing rod 1 for limiting, so as to improve the structural strength of the mounting plate 101 and the limiting support strength at the assembly of the mounting plate 101 and the swing rod 1 by using the limiting ribs 104 extending in different directions; at the same time, the second end of the second limiting rib 1041 away from the mounting plate 101 is freely suspended, and the lower side of the second end is provided with a chamfer to further prevent other equipment from being scratched or damaged.

[0054] Furthermore, the height of the second limiting rib 1041 is the same as that of the limiting rib 104, and their bottoms are flush. Preferably, the vertical height of the limiting rib 104 and the second limiting rib 1041 is less than or equal to half the vertical height of the swing rod 1 and greater than one-quarter of the vertical height of the swing rod 1, so as to reduce the material used for the rib and save costs while ensuring that the limiting rib 104 and the side wall of the swing rod 1 have sufficient contact surface. At the same time, it also allows the side wall of the mounting plate 101 below the limiting rib 104 to be reserved for the mounting rib 105 protruding downward from the cover 102 for assembly.

[0055] In this embodiment, multiple mounting ribs 105 are arranged at intervals along the circumferential direction on the outer peripheral wall of the cover 102.

Each of the opposite screw holes and screw holes is fitted with a screw that passes from top to bottom and is threaded into the top wall of the rocker arm 1, so that the mounting screw of the strong release component mounted on the mounting plate 101 can also fix the mounting plate 101 and the rocker arm 1, so that the same screw has two functions at the same time.

[0063] Meanwhile, in this embodiment, the lower side of the mounting plate 101 is provided with a downwardly protruding positioning protrusion 106, and the top wall of the swing rod 1 is provided with a corresponding positioning groove 1061, which is used to pre-position the mounting plate 101 on the swing rod 1, so that the mounting plate 101, which is guided by the two side limit ribs 104 and slides along the axial direction of the swing rod 1, can achieve sliding pre-position when it slides to the positioning protrusion 106 corresponding to the positioning groove 1061, so that the mounting plate 101 and each screw hole on the swing rod 1 are coaxially aligned, further improving the convenience of assembly between the mounting plate 101 and the swing rod 1;

[0064] Furthermore, preferably, the positioning protrusion 106 is a convex column structure with a radial dimension that gradually narrows from top to bottom; the positioning groove 1061 is a groove structure with a radial dimension equal to the maximum radial dimension of the convex column structure, so that when the positioning protrusion 106 extends into the positioning groove 1061, it can be guided by a tapered column to facilitate the positioning and insertion between the mounting plate 101 and the swing rod 1.

[0065] In this embodiment, a transparent area 107 is provided on the top wall of the cover 102. The transparent area 107 is made of a transparent material, such as glass or plastic. This allows the operator to observe from the outside whether the forced detachment components inside the cover move smoothly, improving the convenience of the operator in assembling, operating, and maintaining the forced detachment structure. Furthermore, the transparent area 107 extends along the axis of the strip-shaped main body mounting cavity 1031, and its width in the left and right directions is not narrower than the width of the mounting guide rail 502 inside the strip-shaped main body mounting cavity 1031, so that the operator can directly observe the operating status of components such as the pull rope 700 and the slider 501 inside the cover 102. Preferably, the cover 102 can be made entirely transparent to further facilitate the operator's observation and judgment of the forced detachment components inside the housing 100.
