Description

Technical Field

[0001] This invention relates to the field of high-altitude sensor deployment technology, specifically to an electrically driven unlocking and release device for a lunar space probe. Background Technology

[0002] The missions of lunar space probes typically involve long-duration, high-risk deep space exploration. The activation and release of the probe are critical steps. To ensure that the probe can successfully enter its predetermined orbit and carry out scientific missions, a reliable unlocking and release device is usually required. In this context, the electric unlocking and release device has become one of the commonly used unlocking methods for space probes due to its high precision, controllability, and small size. The electric unlocking and release device uses a motor to drive the release mechanism and completes the release action under specific commands.

[0003] Chinese invention patent application CN118753502A discloses an electrically driven unlocking and release device for a space probe, comprising a sleeve, a fairing, and a bottom cover. The sleeve contains a chuck, and multiple elongated holes are spaced circumferentially on its sidewalls. Each elongated hole has a release cover inside, and each release cover has a latch at the upper end of its inner plate. Each release cover has a mounting bracket for mounting the space probe at the lower end of its inner plate, with the bottom of each mounting bracket extending beyond the release cover. A motor is mounted on the chuck, and the motor's shaft engages with the unlocking disc. A locking pin is located on the outer edge of the unlocking disc. The device also includes elastic plates located below the motor and corresponding to each release cover for ejecting the space probe. Both ends of each elastic plate are connected to the inner wall of the sleeve via connectors. The device further includes a controller and a height sensor, with the height sensor and motor electrically connected to the controller. This patent, through its structural design of the electrically driven unlocking and release device for a space probe, facilitates assembly, allows for the carrying of multiple or various types of probes, and enables multi-area, multi-height measurement and multi-data acquisition.

[0004] However, the current device has the following problems: the connection between the latch and the main body is unstable and loose, which affects the stability of the entire mechanical system, causing the entire device to shift, affecting the precise operation of other systems of the probe, generating abnormal torque or friction, causing damage to the latch or failure of the unlocking mechanism, causing the connection to loosen or wear further, or even causing the latch to fall off completely, thus affecting the subsequent operation of the probe. Therefore, we propose an electrically driven unlocking and release device for a lunar space probe. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electrically driven unlocking and release device for a lunar space probe, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrically driven unlocking and release device for a lunar space probe, comprising a base column, a housing fixedly connected to the top of the base column, a dome-shaped cover fixedly connected to the top of the housing, a release device disposed on the top of the base column, the release device comprising a fixing frame, the bottom of the fixing frame fixedly connected to the top of the base column, a fixing block fixedly connected to the outer wall of the housing, a connecting rod fixedly connected to the inner wall of the fixing block, limiting blocks fixedly connected to both ends of the connecting rod, the limiting blocks contacting the fixing blocks, a rotating block rotatably connected to the outer wall of the connecting rod, the limiting blocks contacting the rotating blocks, a release cover fixedly connected to the side of the rotating block, and an elongated opening for mounting the release cover on the outer wall of the housing. The release cover has a hole, and a release post is fixedly connected to the inner wall of the release cover. The fixing frame is in contact with the release post. The inner wall of the outer shell is provided with a stabilizing device, which includes a placement plate. The outer wall of the placement plate is fixedly connected to the inner wall of the outer shell. A bidirectional motor is fixedly connected to the bottom of the placement plate. A threaded rod is fixedly connected to one end of the output shaft of the bidirectional motor. An unlocking disc is fixedly connected to the outer wall of the threaded rod. An insert plate is fixedly connected to the top of the release cover. When the bidirectional motor is started, the rotation of the output shaft of the bidirectional motor drives the rotation of the threaded rod, which in turn drives the rotation of the unlocking disc. The rotation of the unlocking disc locks in and out of the insertion hole of the insert plate, enlarging the unlocking disc and its locking hole, and simultaneously enlarging the insert plate and its insertion hole, thereby increasing the contact area between the unlocking disc and the insert plate.

[0007] According to the above technical solution, the stabilizing device further includes a second threaded rod, which is fixedly connected to the output shaft of the bidirectional motor away from the first threaded rod. A threaded sleeve is threadedly connected to the outer wall of the second threaded rod, and a hinged rod is hinged to the side of the threaded sleeve. An airbag suction cup is hinged to the end of the hinged rod away from the threaded sleeve. A gap is left between the airbag of the airbag suction cup and the second threaded rod. The suction cup of the airbag suction cup contacts the release column. A circular hole is opened at the top of the placement plate, through which the output shaft of the bidirectional motor passes. A locking hole for fixing the insert plate is opened on the outer wall of the unlocking plate. An insertion hole for locking the unlocking plate is opened on the side of the insert plate. A square hole is opened on the outer wall of the outer shell, through which the insert plate passes. When the bidirectional motor is started, the rotation of the bidirectional motor output shaft drives the rotation of the second threaded rod. The rotation of the second threaded rod drives the movement of the threaded sleeve, which in turn drives the movement of the hinged rod. The movement of the hinged rod causes the airbag of the airbag suction cup to expand. The expansion of the airbag of the airbag suction cup, through a pipe, causes the suction cup of the airbag suction cup to suck up the release column.

[0008] According to the above technical solution, the outer wall of the shell is provided with a damage prevention device. The damage prevention device includes a side plate one, the side of which is fixedly connected to the outer wall of the shell. The outer wall of the release cover is fixedly connected to a side plate two. The side of the side plate one is fixedly connected to a folding telescopic plate. The side of the folding telescopic plate away from the side plate one is fixedly connected to the side of the side plate two. A gap is left between the side of the folding telescopic plate and the release column. The rotation of the unlocking disc locks out the unlocking disc. The movement of the hinge rod squeezes the airbag of the airbag suction cup. The airbag of the airbag suction cup is squeezed and, through the pipe, drives the suction cup of the airbag suction cup to release the release column, thereby causing the rotating block to rotate around the connecting rod. The rotation of the rotating block drives the rotation of the release cover. The rotation of the release cover drives the rotation of the release column. The rotation of the release column drives the rotation of the side plate two. The rotation of the side plate two causes the folding telescopic plate to expand and extend.

[0009] According to the above technical solution, the damage prevention device further includes a horizontal block, the side of which is fixedly connected to the outer wall of the outer casing. A semicircular block one is fixedly connected to the bottom of the horizontal block. A bottom block is fixedly connected to the side of the folding telescopic plate. A vertical rod is fixedly connected to the top of the bottom block. A sliding plate is slidably connected to the outer wall of the vertical rod. The sliding plate is in contact with the folding telescopic plate. A semicircular block two is fixedly connected to the top of the sliding plate. The circular surface of the semicircular block one of the horizontal block is located on the movement trajectory of the circular surface of the semicircular block two of the sliding plate. A blade is fixedly connected to the side of the sliding plate. A spring is provided between the bottom block and the sliding plate. The rotation of the side plate two causes the folding telescopic plate to extend. The expansion and extension of the plate causes the base block to rotate, which in turn causes the vertical rod to rotate, which in turn causes the sliding plate to rotate, which in turn causes the second semicircular block to rotate. When the second semicircular block of the sliding plate moves to the position of the first semicircular block of the horizontal block, the surface of the first semicircular block of the horizontal block pushes the surface of the second semicircular block of the sliding plate, causing the sliding plate to move downward. The downward movement of the sliding plate causes the blade to move downward. When the surface of the first semicircular block of the horizontal block no longer pushes the second semicircular block of the sliding plate, the sliding plate resets under the elastic force of the corresponding spring and moves upward. The reset of the sliding plate causes the blade to reset, thus realizing the reciprocating motion of the blade.

[0010] According to the above technical solution, the outer wall of the threaded rod is provided with an anti-loosening device, which includes a chuck. The chuck contacts the placement plate, and the inner wall of the chuck is slidably connected to the outer wall of the threaded rod. A spacer nut is threadedly connected to the outer wall of the threaded rod, and the spacer nut contacts the chuck. An unlocking disc contacts the spacer nut, and a fixing nut is threadedly connected to the outer wall of the threaded rod, and the fixing nut contacts the unlocking disc. A circular hole is opened at the top of the chuck, through which the threaded rod passes. When the bidirectional motor is started, the rotation of the output shaft of the bidirectional motor drives the rotation of the threaded rod. The rotation of the threaded rod drives the movement of the spacer nut, thereby clamping the chuck between the placement plate and the spacer nut. The rotation of the threaded rod drives the movement of the fixing nut, thereby replacing the clamping relationship of the chuck.

[0011] This invention provides an electrically driven unlocking and release device for a lunar space probe. It has the following advantages:

[0012] (1) This invention, through the setting of a stabilizing device, enables the bidirectional motor, threaded rod one, unlocking disc, insert plate, insertion hole, locking disc, and locking hole to cooperate. In use, when the bidirectional motor is started, the rotation of the output shaft of the bidirectional motor drives the rotation of threaded rod one, which in turn drives the rotation of the unlocking disc. The rotation of the unlocking disc engages and disengages the insertion hole of the insert plate, enlarging the unlocking disc and its locking hole, and enlarging the insert plate and its insertion hole, thereby increasing the contact area between the unlocking disc and the insert plate. This improves the stability of the locking, helps to disperse external forces, reduces the possibility of loosening, enhances the device's vibration and impact resistance, effectively distributes the force brought by vibration and impact, prevents the lock from loosening or accidentally unlocking, and makes the force distribution more uniform, reducing excessive local pressure concentration, thereby reducing the risk of wear and fatigue damage. Simultaneously, the cooperation of threaded rod two, threaded sleeve, hinge rod, airbag suction cup, and release column enables the bidirectional motor to be started. The rotation of the output shaft drives the rotation of the second threaded rod, which in turn drives the movement of the threaded sleeve. The movement of the threaded sleeve drives the movement of the hinge rod, which in turn drives the expansion of the air bladder suction cup. The expansion of the air bladder suction cup, through the pipe, causes the suction cup to grip the release column. The air bladder suction cup provides a uniform and adjustable suction force, thereby enhancing the locking stability of the unlocking system. This results in a more uniform and stronger fixation of the components, effectively improving the contact force and stability during locking. It ensures that the unlocking device remains stable in complex environments with high vibration and impact, absorbing some vibration and impact energy, thus reducing the impact on the locking system and preventing the locking components from loosening or falling off during operation. This helps improve the device's vibration and impact resistance. Within a certain range, it adapts to different shapes and surface unevenness, adjusting its own shape by inflating or deflating to compensate for errors and ensure a more stable lock.

[0013] (2) This invention, through the setting of the anti-damage device, enables the cooperation of the unlocking disc, hinge rod, airbag suction cup, release column, rotating block, connecting rod, release cover, side plate two, and folding telescopic plate. The rotation of the unlocking disc locks out the unlocking disc, the movement of the hinge rod compresses the airbag of the airbag suction cup, and the compressed airbag of the airbag suction cup, through the pipe, drives the suction cup of the airbag suction cup to release the release column, thereby causing the rotating block to rotate around the connecting rod. The rotation of the rotating block drives the rotation of the release cover, the rotation of the release cover drives the rotation of the release column, and the rotation of the release column drives the rotation of side plate two. The rotation of side plate two causes the folding telescopic plate to expand. The structure provides a physical barrier, offering a long-term protective layer to withstand small collisions from debris in space. It effectively disperses collision energy, absorbs some impact force, and reduces the risk of debris directly impacting the core structure, preventing structural damage and ensuring continued stable operation. This improves the overall mission survivability and reduces direct exposure of the probe surface to potential hazards. Simultaneously, the rotation of side plate two, the folding telescopic plate, the base block, the vertical rod, the sliding plate, the second semicircular block, the horizontal block, the first semicircular block, and the blade ensures proper coordination. The expansion and extension cause the base block to rotate, which in turn causes the vertical rod to rotate, which in turn causes the sliding plate to rotate, which in turn causes the second semicircular block to rotate. When the second semicircular block of the sliding plate moves to the position of the first semicircular block of the horizontal block, the surface of the first semicircular block of the horizontal block pushes the surface of the second semicircular block of the sliding plate, causing the sliding plate to move downwards. The downward movement of the sliding plate causes the blade to move downwards. When the surface of the first semicircular block of the horizontal block no longer pushes the second semicircular block of the sliding plate, the sliding plate returns to its original position under the elastic force of the corresponding spring and moves upwards. The return of the sliding plate causes the blade to move downwards. The resetting mechanism enables the blades to reciprocate, breaking up small debris flying from space and dispersing their energy upon impact. This allows for early debris removal, reducing the destructive force on the equipment and preventing structural damage. It also reduces the risk of collisions between small debris and folding telescopic plates and other sensitive structures, preventing debris from lingering around the equipment and thus reducing the probability of failure. This self-protection mechanism reduces the risk of damage and improves the system's adaptability, especially during long-duration space missions, effectively reducing accidental damage caused by debris collisions.

[0014] (3) The present invention, through the setting of the anti-loosening device, enables the bidirectional motor, threaded rod one, spacer nut, chuck, placement plate, and fixing nut to cooperate. When the bidirectional motor is started, the rotation of the output shaft of the bidirectional motor drives the rotation of threaded rod one, and the rotation of threaded rod one drives the movement of spacer nut, thereby clamping the chuck and clamping it between the placement plate and spacer nut. The rotation of threaded rod one drives the movement of fixing nut, thereby replacing the chuck's snap-fit ​​relationship, achieving precise control and positioning, reducing the risk of release failure or loosening caused by inaccurate mechanical snap-fit, providing more stable and precise locking and unlocking actions, not relying on complex and easily damaged parts, increasing the reliability of the system, reducing the risk of mechanical failure, and having stronger adaptability. Especially in vacuum, extreme temperature or radiation environments, the device can work more stably and is not easily affected by the space environment, providing a smooth and adjustable unlocking process. Compared with the traditional mechanical snap-fit ​​method, the device can achieve more gentle and precise control during the opening process, thereby avoiding sudden vibration or irregular unlocking, reducing interference to other systems, and improving operational safety.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figures 1-8One embodiment of the present invention is as follows: an electrically driven unlocking and release device for a lunar space probe, comprising a base column 1, a housing 2 fixedly connected to the top of the base column 1, a dome cover 3 fixedly connected to the top of the housing 2, a release device 4 provided on the top of the base column 1, the release device 4 comprising a fixing frame 41, the bottom of the fixing frame 41 fixedly connected to the top of the base column 1, a fixing block 42 fixedly connected to the outer wall of the housing 2, a connecting rod 43 fixedly connected to the inner wall of the fixing block 42, a limiting block 44 fixedly connected to both ends of the connecting rod 43, the limiting block 44 contacting the fixing block 42, a rotating block 45 rotatably connected to the outer wall of the connecting rod 43, the limiting block 44 contacting the rotating block 45, a release cover 46 fixedly connected to the side of the rotating block 45, an elongated hole 8 for installing the release cover 46 on the outer wall of the housing 2, and a fixed inner wall of the release cover 46. A release post 47 is connected, and a fixing bracket 41 contacts the release post 47. A stabilizing device 5 is provided on the inner wall of the outer casing 2. The stabilizing device 5 includes a placement plate 51. The outer wall of the placement plate 51 is fixedly connected to the inner wall of the outer casing 2. A bidirectional motor 52 is fixedly connected to the bottom of the placement plate 51. A threaded rod 53 is fixedly connected to the output shaft of one end of the bidirectional motor 52. An unlocking disc 54 is fixedly connected to the outer wall of the threaded rod 53. An insert plate 55 is fixedly connected to the top of the release cover 46. Through the above structure, the stability of the locking is improved, which helps to disperse external forces, reduce the possibility of loosening, improve the device's resistance to vibration and impact, effectively share the force brought by vibration and impact, avoid the lock from loosening or accidental unlocking, and make the force distribution more uniform, reduce excessive local pressure concentration, thereby reducing the risk of wear and fatigue damage.

[0028] The stabilizing device 5 also includes a second threaded rod 56, which is fixedly connected to the output shaft of the bidirectional motor 52 at the end away from the first threaded rod 53. A threaded sleeve 57 is threadedly connected to the outer wall of the second threaded rod 56. A hinged rod 58 is hinged to the side of the threaded sleeve 57. An airbag suction cup 59 is hinged to the end of the hinged rod 58 away from the threaded sleeve 57. A gap is left between the airbag of the airbag suction cup 59 and the second threaded rod 56. The suction cup of the airbag suction cup 59 contacts the release column 47. A circular hole 510 is opened at the top of the placement plate 51, through which the output shaft of the bidirectional motor 52 passes. A locking hole 511 for fixing the insert plate 55 is opened on the outer wall of the unlocking disc 54. An insertion hole 512 for locking the unlocking disc 54 is opened on the side of the insert plate 55. The outer wall of the outer shell 2... A square hole 513 is provided through the insert plate 55. With the above structure, the airbag suction cup 59 can provide a uniform and adjustable suction force, thereby enhancing the locking stability of the unlocking system. This achieves a more uniform and stronger fixation of the components, effectively improving the contact force and stability during locking. It ensures that the unlocking device remains stable in complex environments such as high vibration and impact. It can absorb some vibration and impact energy, thereby reducing the impact on the locking system and preventing the locking components from loosening or falling off during operation. It helps to improve the device's vibration and impact resistance. It can adapt to different shapes and surface unevenness within a certain range. By inflating or deflating, it can adjust its own shape to compensate for errors and ensure a more stable lock.

[0029] The outer wall of the outer shell 2 is equipped with a damage prevention device 6, which includes a side plate 61. The side of the side plate 61 is fixedly connected to the outer wall of the outer shell 2. The outer wall of the release cover 46 is fixedly connected to a side plate 62. The side of the side plate 61 is fixedly connected to a folding telescopic plate 63. The side of the folding telescopic plate 63 away from the side plate 61 is fixedly connected to the side of the side plate 62. A gap is left between the side of the folding telescopic plate 63 and the release post 47. Through the above structure, a certain physical barrier is provided, which can provide a long-term protective layer to resist small collisions with small debris in space, effectively disperse the energy of the collision, absorb some of the impact force, reduce the risk of debris directly hitting the core structure, prevent damage to the structure in the device, ensure that the device can continue to operate stably, improve the overall survivability of the mission, and reduce the direct exposure of the probe surface to potential dangers.

[0030] The damage prevention device 6 also includes a horizontal block 64, the side of which is fixedly connected to the outer wall of the housing 2. A semicircular block 65 is fixedly connected to the bottom of the horizontal block 64. A bottom block 66 is fixedly connected to the side of the folding telescopic plate 63. A vertical rod 67 is fixedly connected to the top of the bottom block 66. A sliding plate 68 is slidably connected to the outer wall of the vertical rod 67. The sliding plate 68 is in contact with the folding telescopic plate 63. A semicircular block 69 is fixedly connected to the top of the sliding plate 68. The circular surface of the semicircular block 65 of the horizontal block 64 is located on the movement trajectory of the circular surface of the semicircular block 69 of the sliding plate 68. A blade 610 is fixedly connected to the side of the sliding plate 68. The bottom block 66 and the sliding plate 68 are connected to the sliding plate 63. A spring 611 is installed between the plates 68. Through the above-mentioned structure, small debris flying in from space is broken up and dispersed, so that the energy of the debris is dispersed during the impact. The debris can be eliminated in the early stage, thereby reducing the destructive force on the equipment, preventing small debris from damaging the structure in the device, reducing the risk of small debris colliding with the folding telescopic plate 63 and other sensitive structures, avoiding small debris from being present around the equipment for a long time, reducing the probability of equipment failure, realizing self-protection, reducing the risk of damage, and improving the system's adaptability. Especially in long-term space missions, it can effectively reduce accidental damage caused by debris collisions.

[0031] In use, the bidirectional motor 52 is started. The rotation of the output shaft of the bidirectional motor 52 drives the rotation of the threaded rod 53. The rotation of the threaded rod 53 drives the rotation of the unlocking disc 54. The rotation of the unlocking disc 54 engages and disengages the insertion hole 512 of the insert plate 55, enlarging the unlocking disc 54 and its locking hole 511, and simultaneously enlarging the insert plate 55 and its insertion hole 512. This increases the contact area between the unlocking disc 54 and the insert plate 55, thereby improving the stability of the locking, helping to disperse external forces, reducing the possibility of loosening, enhancing the device's vibration and impact resistance, effectively distributing the force brought by vibration and impact, preventing the lock from loosening or accidentally unlocking, and making the force distribution more uniform, reducing excessive local pressure concentration, thereby reducing the risk of wear and fatigue damage. Simultaneously, the bidirectional motor 52 is started, and the rotation of the output shaft of the bidirectional motor 52 drives the rotation of the threaded rod 56. The rotation of the threaded rod 56... The movement of the threaded sleeve 57 drives the movement of the hinge rod 58, which in turn causes the airbag of the airbag suction cup 59 to expand. This expansion, through a pipe, causes the suction cup of the airbag suction cup 59 to grip the release column 47. The airbag suction cup 59 provides a uniform and adjustable suction force, thereby enhancing the locking stability of the unlocking system. This results in a more uniform and stronger fixation of the components, effectively improving the contact force and stability during locking. It ensures the unlocking device remains stable in complex environments with high vibration and impact, absorbing some vibration and impact energy to reduce the impact on the locking system. This prevents the locking components from loosening or falling off during operation, helping to improve the device's vibration and impact resistance. It can adapt to different shapes and surface unevenness within a certain range, adjusting its shape by inflating or deflating to compensate for errors and ensure a more stable lock.

[0032] The rotation of the unlocking disc 54 releases the locking mechanism. The movement of the hinge rod 58 compresses the airbag of the airbag suction cup 59. The compression of the airbag suction cup 59, through the pipe, causes the suction cup to release the release column 47, thereby causing the rotating block 45 to rotate around the connecting rod 43. The rotation of the rotating block 45 causes the release cover 46 to rotate, which in turn causes the release column 47 to rotate. The rotation of the release column 47 causes the side plate 62 to rotate, which in turn causes the folding telescopic plate 63 to expand and extend, providing a certain physical barrier and a long-term protective layer. This effectively disperses the energy of small collisions with debris in space, absorbs some of the impact force, reduces the risk of debris directly impacting the core structure, prevents structural damage to the device, ensures the device can continue to operate stably, and improves the overall survivability of the mission. It also reduces the direct exposure of the probe surface to potential hazards. Simultaneously, the rotation of side plate 62 causes the folding telescopic plate 63 to expand, which in turn drives the rotation of the base block 66. The rotation of the base block 66 drives the rotation of the vertical rod 67, which in turn drives the rotation of the sliding plate 68. The movement drives the rotation of the second semicircular block 69. When the second semicircular block 69 of the sliding plate 68 moves to the position of the first semicircular block 65 of the horizontal block 64, the circular surface of the first semicircular block 65 of the horizontal block 64 pushes the circular surface of the second semicircular block 69 of the sliding plate 68, causing the sliding plate 68 to move downward. The downward movement of the sliding plate 68 causes the blade 610 to move downward. When the circular surface of the first semicircular block 65 of the horizontal block 64 no longer pushes the second semicircular block 69 of the sliding plate 68, the sliding plate 68 resets under the elastic force of the corresponding spring 611 and moves upward. The reset of the sliding plate 68 causes the blade 610 to reset, thus realizing... The reciprocating motion of the blade 610 breaks up small debris flying from space, dispersing the energy of the debris upon impact and eliminating it early, thus reducing the destructive force on the equipment. This prevents small debris from damaging the structure of the device, reduces the risk of collisions between small debris and the folding telescopic plate 63 and other sensitive structures, avoids the long-term presence of small debris around the equipment, reduces the probability of equipment failure, achieves self-protection, reduces the risk of damage, and improves the system's adaptability. Especially in long-duration space missions, it can effectively reduce accidental damage caused by debris collisions.

[0033] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the outer wall of the threaded rod 53 is provided with an anti-loosening device 7. The anti-loosening device 7 includes a chuck 71, which contacts the placement plate 51. The inner wall of the chuck 71 is slidably connected to the outer wall of the threaded rod 53. A spacer nut 72 is threadedly connected to the outer wall of the threaded rod 53, and the spacer nut 72 contacts the chuck 71. An unlocking disc 54 contacts the spacer nut 72. A fixing nut 73 is threadedly connected to the outer wall of the threaded rod 53, and the fixing nut 73 contacts the unlocking disc 54. A circular hole 74 is opened at the top of the chuck 71, through which the threaded rod 53 passes. Through the above-described structure, precise control is achieved. The device improves locking and unlocking by reducing the risk of release failure or loosening due to inaccurate mechanical locking. It provides more stable and precise locking and unlocking actions, does not rely on complex and easily damaged components, increases system reliability, reduces the risk of mechanical failure, and has greater adaptability. Especially in vacuum, extreme temperature, or radiation environments, the device can work more stably and is less affected by the space environment. It provides a smooth and adjustable unlocking process. Compared with traditional mechanical locking methods, the device can achieve smoother and more precise control during the opening process, thereby avoiding sudden vibrations or irregular unlocking, reducing interference with other systems, and improving operational safety.

[0034] In use, the bidirectional motor 52 is started. The rotation of the output shaft of the bidirectional motor 52 drives the rotation of the threaded rod 53. The rotation of the threaded rod 53 drives the movement of the spacer nut 72, thereby clamping the chuck 71 and making the chuck 71 clamp between the placement plate 51 and the spacer nut 72. The rotation of the threaded rod 53 drives the movement of the fixing nut 73, thereby replacing the snap-fit ​​relationship of the chuck 71, achieving precise control and positioning, reducing the risk of release failure or loosening caused by inaccurate mechanical snap-fit, providing more stable and precise locking and unlocking actions, not relying on complex and easily damaged parts, increasing system reliability, reducing the risk of mechanical failure, and having stronger adaptability. Especially in vacuum, extreme temperature or radiation environments, the device can work more stably and is not easily affected by the space environment, providing a smooth and adjustable unlocking process. Compared with the traditional mechanical snap-fit ​​method, the device can achieve smoother and more precise control during the opening process, thereby avoiding sudden vibration or irregular unlocking, reducing interference with other systems, and improving operational safety.
