Description

Technical Field

[0001] The present invention relates to the field of aerospace technology, and in particular to a compression release device. Background Art

[0002] A hold-down release mechanism is a mechanical device used to securely connect a spacecraft's main body and accessories, or between components, during launch, and to release the restraints as required after entering orbit. Spacecraft systems such as solar panels and deployable antennas utilize this type of mechanism.

[0003] Current compression release devices usually use pyrotechnic devices or non-pyrotechnic devices to achieve compression release. However, since pyrotechnic devices use the energy generated by the combustion or explosion of gunpowder to complete the release function, they usually have disadvantages such as large explosion impact force, safety hazards, and non-recyclability. Non-pyrotechnic devices often use hot knives to cut Kevlar ropes. Although this reduces some impact, the preload force they withstand is small and the application scenarios are relatively limited. They are generally only suitable for small satellites. Summary of the Invention

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] It should be noted that in the coordinate system XYZ provided herein, the positive direction of the X axis represents the right, the negative direction of the X axis represents the left, the positive direction of the Y axis represents the back, the negative direction of the Y axis represents the front, the positive direction of the Z axis represents the top, and the negative direction of the Z axis represents the bottom. At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0022] An embodiment of the present invention provides a compression and release device, including a locking assembly 1 and an unlocking assembly 2, wherein the locking assembly 1 includes a locking rope 10, a locking sleeve 11, a petal clamp 12, a compression rod 14 and a fixing seat 15, wherein the fixing seat 15 is slidably connected to the locking sleeve 11, and the locking rope 10 is used to lock the locking sleeve 11 on the fixing seat 15, and the locking sleeve 11 is used to be sleeved on the petal clamp 12, and the petal clamp 12 has a closed state and a separated state. When the petal clamp 12 is in the closed state, the petal clamp 12 clamps the compression rod 14, and when the petal clamp 12 is in the separated state, the petal clamp 12 is separated from the compression rod 14, and the unlocking assembly 2 is used to disconnect the locking rope 10 to separate the locking sleeve 11 from the fixing seat 15.

[0023] It should be noted that the clamping rod 14 can usually be used to connect accessories that need to be unfolded and released (such as solar wings or deployable antennas, etc.), and the petal clamp 12 can also be used to directly connect to the main device (such as a spacecraft or aircraft, etc.) to achieve the compression and release function between the accessory and the main device. Although the following text only uses the compression and release between the solar wing and the spacecraft as an example, for other structures or accessories that need to achieve the compression and release function, the compression and release device can also be used, such as deployable sun visors, etc., and no specific restrictions are made here.

[0024] Specifically, combined Figures 1 to 3 As shown, the locking sleeve 11 of the locking assembly 1 is provided with a through hole at its own central axis (i.e., the Z axis in the figure), and the petal clamp 12 can be formed by two or more clamps. A slot structure is formed by closing the petal clamp 12, so that the clamping rod 14 is inserted into the slot structure and clamped and limited. The petal clamp 12 in the closed state can be inserted into the through hole of the locking sleeve 11 and limited by the locking sleeve 11. The fixing seat 15 is connected to the corresponding accessory or base 13 (to be introduced later) through fasteners, and the locking rope 10 can be a Kevlar rope.

[0025] Exemplarily, the process of the compression and release device to realize the compression and release of the solar wing (that is, the compression rod 14 is connected to the solar wing, and the base 13 is connected to the spacecraft) is as follows: the compression rod 14 is clamped by the petal clamp 12, and the locking sleeve 11 is placed on the petal clamp 12 in the closed state, and the locking is achieved by tightening the locking rope 10 and winding the locking sleeve 11 on the fixing seat 15. The movement of the locking sleeve 11 relative to the petal clamp 12 is restricted, so that the petal clamp 12 can remain in the closed state, thereby realizing the compression and locking of the solar wing relative to the spacecraft; the unlocking component 2 can The locking rope 10 is disconnected by mechanical cutting or other means, so that the locking sleeve 11 can be moved away from the fixing seat 15 (the power for the locking sleeve 11 and the fixing seat 15 to move away from each other can be achieved by electromagnetic force or other means), so that the petal clamp 12 in the closed state is no longer limited by the locking sleeve 11, and the petal clamp 12 is in a separated state (the power for the petal clamp 12 to switch between the closed state and the separated state can be achieved by electromagnetic force or other means), and the clamping rod 14 is no longer clamped, thereby realizing the unlocking and release of, for example, the solar wing connected to the clamping rod 14 relative to the spacecraft.

[0026] It should be noted that the closed state and separated state of the petal clamp 12 refer to the adjacent clamps of the petal clamp 12 being brought together and abutting against each other and being away from each other and separated. Usually, at least two clamps can be brought together to form a hole groove structure, and the clamping rod 14 and the base 13 can be placed in the hole groove structure when the petal clamp 12 is in the separated state, and then the petal clamp 12 is in the closed state to achieve the clamping function; when the clamps are away from each other and the petal clamp 12 is in the separated state, the hole groove structure fails, so that the clamping rod 14 is no longer clamped, and the release function is achieved. On this basis, providing a concave-convex structure or a thread in the hole groove structure can achieve a better clamping effect, which is not specifically limited here; in addition, the number of clamps of the petal clamp 12 can be designed according to specific needs, which is not specifically limited here.

[0027] The compression and release device of the present invention is equipped with a limiting petal clamp 12 through a locking sleeve 11, so that the petal clamp 12 remains in a closed state, and the locking sleeve 11 is locked to the fixing seat 15 through the locking rope 10, thereby maintaining the clamping of the petal clamp 12 on the compression rod 14, realizing a compression and locking function between, for example, the solar wing and the spacecraft; the locking rope 10 is disconnected by the unlocking component 2, so that the locking sleeve 11 can move in a direction away from the fixing seat 15 and the petal clamp 12, and the petal clamp 12 switches from a closed state to a separated state, thereby releasing the compression rod 14, realizing an unlocking and releasing function between, for example, the solar wing and the spacecraft; the compression and release device of the present invention is equipped with a petal clamp 12 through the locking sleeve 11 to realize a compression and locking function, can withstand a greater preload, is not limited to small satellites, and improves applicability; the unlocking and releasing function is realized by disconnecting the locking rope 10 by the unlocking component 2. Compared with the design of pyrotechnic products, it is safer and more environmentally friendly, can be reused, and reduces the impact force on other components.

[0028] Optionally, the locking assembly 1 also includes a first winding post 16 and a second winding post 17, and the first winding post 16 and the second winding post 17 are respectively arranged on the locking sleeve 11 and the fixing seat 15, and the locking rope 10 is used to be wound around the first winding post 16 and the second winding post 17 and is in a tensioned state.

[0029] Specifically, combined Figure 1 As shown, two second winding pins 17 are threadedly connected to the fixing base 15 on both sides along the positive and negative directions of the X-axis in the figure, and two first winding pins 16 are threadedly connected to the locking sleeve 11 on both sides along the positive and negative directions of the X-axis in the figure. There are two locking ropes 10 and two unlocking components 2. One locking rope 10 is wound around the first winding pin 16 and the second winding pin 17 on one side to tighten the locking sleeve 11 and the fixing base 15, and the two ends of the locking rope 10 are fixed to an unlocking component 2 on the same side; the first winding pin 16 and the second winding pin 17 on the other side are tightened by another locking rope 10, and the two ends of the locking rope 10 are fixed to an unlocking component 2 on the same side. The unlocking component 2 can use a clamping claw to clamp and release the rope ends to achieve locking and release. In this way, by fixing the locking sleeve 11 with the locking ropes 10 symmetrically arranged on both sides, the locking sleeve 11 can be prevented from being stuck due to uneven force during the compression, locking and unlocking processes. (The locking rope 10 in this solution is not shown in the figure)

[0030] In this way, the locking rope 10 is conveniently wound around the first winding post 16 and the second winding post 17 so that the locking sleeve 11 is locked on the fixing seat 15, thereby achieving a more stable compression and locking effect.

[0031] Optionally, the split clamp 12 is a split nut. When the split nut is in a closed state, a threaded hole is formed in the split nut, and the pressing rod 14 is threadedly connected to the split nut at the threaded hole.

[0032] Specifically, combined Figure 1 and Figure 2 As shown, the upper end of the split clamp 12 (the end along the positive Z-axis in the figure) is provided with a threaded hole, that is, the split clamp 12 is a split nut. When the split nut is in the separated state, the clamping rod 14 cannot be threadedly connected to the split nut, thus releasing the clamping rod 14. When the split nut is in the closed state, the clamping rod 14 is threadedly connected to the split nut, thus clamping the clamping rod 14.

[0033] In this way, the threaded connection between the split nut and the pressing rod 14 can make the connection between, for example, the solar wing and the spacecraft more stable to a certain extent.

[0034] Optionally, the locking sleeve 11 is axially provided with a first through hole 111 and a second through hole 112 that are interconnected, the cross-sectional area of the second through hole 112 is larger than the cross-sectional area of the first through hole 111, the hole wall of the first through hole 111 is used to abut against the split clamp 12 when the split clamp 12 is in a closed state, and the second through hole 112 is used to accommodate the split clamp 12 in a separated state.

[0035] Specifically, combined Figure 1 and Figure 2 As shown, the first through hole 111 has a larger cross-sectional area than the second through hole 112, and the two are interconnected to form a through hole structure, that is, a stepped hole structure that is narrow at the top and wide at the bottom along the Z axis in the figure is formed. The first through hole 111 can just be mounted on the petal clamp 12 in the closed state, and when the locking rope 10 is disconnected, the locking sleeve 11 moves relative to the petal clamp 12 along the positive direction of the Z axis, so that the petal clamp 12 enters the second through hole 112, and the petal clamp 12 enters the separation state to release the clamping rod 14, and the petal clamp 12 can be accommodated in the second through hole 112 (the petal clamp 12 can also directly abut against the hole wall of the second through hole 112). In addition, the petal clamp 12 in the closed state can also form a corresponding stepped axis structure.

[0036] In this way, the time it takes to unlock the petal clamp 12 can be changed by designing different lengths of the first through hole 111 and the second through hole 112. For example, by shortening the length of the first through hole 111, the time it takes for the petal clamp 12 to enter the separated state from the closed state can be shortened, thereby accelerating the speed at which the compression release device can achieve unlocking and release. At the same time, the petal clamp 12 in the separated state is accommodated in the second through hole 112 to prevent the petal clamp 12 from being thrown into the external environment.

[0037] Optionally, the locking assembly 1 also includes a clamping screw 18 and an adjusting screw 19, and the clamping screw 18 and the adjusting screw 19 are threadedly connected to the locking sleeve 11. One end of the locking rope 10 is wrapped around the adjusting screw 19 and is clamped to the locking sleeve 11 through the clamping screw 18, and the other end is wrapped around the second winding post 17 through the first winding post 16.

[0038] Specifically, combined Figure 3 As shown, a corresponding threaded hole is opened at one end of the locking sleeve 11 along the positive direction of the Z axis in the figure, and the end of the locking rope 10 is pressed into the corresponding threaded hole by the tightening screw 18 to achieve compression and fixation. Then the locking rope 10 is wound around the adjusting screw 19, and then wound around the second winding post 17 and the first winding post 16.

[0039] In this way, the two ends of the locking rope 10 are fixed more firmly by the tightening screw 18, and the pre-tightening force of the locking rope 10 can be adjusted by adjusting the pre-tightening force of the adjusting screw 19 or the number of turns of the locking rope 10 around the adjusting screw 19, so that the compression release device is suitable for occasions with different pre-tightening force requirements.

[0040] Optionally, one of the fixing seat 15 and the locking sleeve 11 is provided with a guide column, and the other is provided with a guide groove, and the guide column is slidably connected to the guide groove.

[0041] Specifically, combined Figure 1 and Figure 2 As shown, the fixing seat 15 is provided with a guide column pointing vertically upward (ie, along the positive direction of the Z axis in the figure), and the locking sleeve 11 is provided with a guide groove, and the guide column is inserted into the guide groove to achieve a sliding connection.

[0042] In this way, the movement of the locking sleeve 11 away from the fixing seat 15 is guided by the guide post and the guide groove, thereby avoiding the problem that the locking sleeve 11 may be tilted and stuck.

[0043] Optionally, it also includes a first elastic member 4 and a second elastic member 5, and the petal clamp 12 includes two clamps, the two ends of the first elastic member 4 are respectively connected to the fixing seat 15 and the locking sleeve 11, and the two ends of the second elastic member 5 are respectively connected to the two clamps.

[0044] Specifically, combined Figure 1 and Figure 2 As shown, a split clamping block 12 is formed by two clamping blocks, wherein a spring is provided between the two clamping blocks as a second elastic member 5 , and a spring is provided between the fixing seat 15 and the locking sleeve 11 as a first elastic member 4 .

[0045] In this way, the second elastic member 5 can convert potential energy into kinetic energy to drive the petal clamp 12 from the closed state to the separated state, and the first elastic member 4 can convert potential energy into kinetic energy to drive the locking sleeve 11 to move away from the fixed seat 15, so that the compression release device can be automatically unlocked and released smoothly after the locking rope 10 is disconnected.

[0046] Optionally, the unlocking assembly 2 includes a heating wire 21, an elastic steel sheet 22 and a mounting seat 23, the elastic steel sheet 22 is mounted on the mounting seat 23, the heating wire 21 is connected to the elastic steel sheet 22, and is used to abut against the locking rope 10.

[0047] Specifically, combined Figure 3 As shown, two elastic steel sheets 22 are mounted on the base 13 through a mounting seat 23 (to be introduced later), and both ends of the heating wire 21 are respectively connected to the elastic steel sheets 22 and abut against the locking rope 10. The heating wire 21 adopts the hot knife principle. After power is turned on, the heating wire 21 can melt the locking rope 10.

[0048] It should be understood that the mounting seat 23 can also be installed on other components such as spacecraft as needed, as long as it can abut against the locking rope 10 when compressed and locked.

[0049] Thus, compared to mechanical cutting, melting the locking rope 10 by heating the wire 21 (i.e., hot knife) is more suitable for some locking ropes 10 that can withstand a larger pre-tightening force and are not easy to cut, and reduces the impact force compared to pyrotechnic products.

[0050] Optionally, the locking assembly 1 further includes a base 13 , the base 13 is provided with a protrusion 131 , the protrusion 131 is provided with an annular groove 1311 , the split clamp 12 is used to form an annular protrusion 121 in a closed state, and the annular protrusion 121 is used to be inserted into the annular groove 1311 .

[0051] Specifically, combined Figure 1 and Figure 2 As shown, the base 13 is provided with a cylindrical structure protrusion 131 facing the positive direction of the Z axis in the figure, and an annular groove 1311 is provided on the protrusion 131. The lower end of the petal clamp 12 forms a hole groove structure when it is in the closed state. The petal clamp 12 is provided with an annular protrusion 121 located in the hole groove structure. After the annular protrusion 121 is inserted into the annular groove 1311, the petal clamp 12 is sleeved by the locking sleeve 11 to clamp the clamping rod 14 and the base 13.

[0052] In this way, the petal clamp 12 can be inserted into the annular groove 1311 of the base 13 through the annular protrusion 121, so that the clamping rod 14 and the base 13 can be clamped and locked. For example, the solar wing can be connected through the clamping rod 14, and the spacecraft can be connected through the base 13, thereby improving the stability of the clamping and locking.

[0053] Optionally, a shell 3 connected to the base 13 is further included, the shell 3 is covered on the locking sleeve 11 and the fixing seat 15 , and the pressing rod 14 extends out of the shell 3 at one end away from the petal clamp 12 .

[0054] Specifically, combined Figure 1 and Figure 2 As shown, the shell 3 is covered with the locking sleeve 11 and the fixing seat 15 and is connected to the base 13 through fasteners. The shell 3 is installed on the base 13 and then connected to the fixing seat 15. An opening is provided at the upper end of the shell 3 for the clamping rod 14 to pass through. The shell 3 is hollowed out on both sides of the positive and negative directions of the X-axis in the figure to facilitate relative movement between the first winding post 16 and the second winding post 17.

[0055] In this way, the shell 3 can protect the components of the compression release device and prevent some of the components from entering the external environment.

[0056] Optionally, the locking rope 10 is a Dyneema rope.

[0057] Specifically, the locking rope 10 adopts Figure 3 The locking rope 10 is wound and tightened in the manner shown in the figure, and the locking rope 10 adopts a powerful horse rope with stable performance and high strength.

[0058] In this way, the use of a Dyneema rope as the locking rope 10 can withstand a greater pre-tightening force than a Kevlar rope, and is more suitable for scenarios with higher pre-tightening force requirements, such as large satellites.

[0059] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
