Description

Technical Field

[0001] This invention relates to the field of aerospace mechanism design, and more particularly to a rope connection unlocking mechanism for locking irregularly shaped objects. Background Technology

[0002] With the development of space science and technology, the development technology of spacecraft both domestically and internationally is becoming increasingly mature. Against this backdrop, spacecraft shapes are becoming increasingly complex, placing higher demands on the mechanical environment, including impacts and vibrations, generated during transportation or launch separation. For example... Figure 1 A grid fin is shown for collecting data from the bottom of a rocket. Figure 1 The illustrated gate rudder uses a suspected program to control resistance heating to unlock the rope-connected unlocking mechanism, thus achieving constraint on the contact gate rudder. However, the current unlocking and separation mechanism can only connect to regular objects and requires prior coordination. For connecting and unlocking irregular objects, using traditional connection and unlocking schemes would result in high design and development costs and long development cycles. Therefore, there is an urgent need to design a rope-connected unlocking mechanism for locking irregularly shaped objects. Summary of the Invention

[0003] The technical problem solved by this invention is that, in the current technology, traditional point-type connection and unlocking devices cannot connect and unlock irregularly shaped objects, and the development cost is high and the cycle is long. Therefore, a rope connection and unlocking mechanism for locking irregularly shaped objects is proposed.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0005] A rope-connected unlocking mechanism for locking irregularly shaped objects is characterized by comprising a fusible component 1, a pull rope 2, an adjusting component 3, a locking force prediction component 4, and a main body collecting component 5. The fusible component 1 is connected to the locking force prediction component 4 via the pull rope 2. The locking force prediction component 4 is connected to the adjusting component 3 via the pull rope 2. The adjusting component 3 is connected to the fusible component 1 via the pull rope 2. The main body collecting component 5 is directly connected to both the fusible component 1 and a ground device. The fusible component 1 is connected to the ground device via the main body collecting component 5.

[0006] The fuse component 1 enables locking and unlocking by power-on, the adjustment component 3 enables tightening of the pull rope 2, the locking force prediction component 4 determines the magnitude of the pre-tightening force and provides a basis for the tightening position of the adjustment component 3, and the main body collection component 5 enables the pull rope (2) to be pulled and collected when unlocking.

[0007] Furthermore, the pull rope 2 is a Kevlar pull rope.

[0008] Furthermore, the fuse assembly 1 includes two fuse circuit assemblies symmetrically arranged on the support 1-1 and two support covers 1-2 for sealing. The fuse circuit assembly includes a fuse resistor 1-5 and a fuse wire 1-6 installed on the base 1-3. The fuse resistor 1-5 achieves resistance heating when external power is applied. The fuse wire 1-6 is in tight contact with the fuse resistor 1-5 and has a loop and extends out of the fuse assembly 1.

[0009] Furthermore, the fuse circuit assembly also includes a clamping cover 1-4, an adjusting screw 1-7, an adjusting nut 1-8, and a slider 1-9 installed on the base 1-3. The fuse resistor 1-5 heats up when externally energized. The fuse wire 1-6 is fixedly connected to the slider 1-9, with a loop extending out of the fuse assembly 1. The slider 1-9 slides in the base 1-3. The adjusting screw 1-7 is fixedly connected to the slider 1-9 and passes through the through hole of the base 1-3 to be screwed to the adjusting nut 1-8. By turning the adjusting screw 1-7, the position of the slider 1-9 in the base 1-3 can be adjusted, thereby adjusting the position of the loop of the fuse wire 1-6. The clamping cover 1-4 is a protective cover after the fuse resistor 1-5 and the fuse wire 1-6 are installed.

[0010] Furthermore, the fusible resistors 1-5 are two independent resistors a and b. The two ends of resistor a are soldered to the aviation pin interface (a+, a-) through wires (a+, a-), and the two ends of resistor b are soldered to the aviation pin interface (b+, b-) through wires (b+, b-). The wires and the aviation pin interfaces (a+, a-) and (b+, b-) extend out of the fusible assembly 1 through the support cover 1-2, so that the resistors heat up when the external power is applied.

[0011] Furthermore, two screws are installed on the slider 1-9. After the fuse wire 1-6 is folded in half, it is installed on the two screws by figure-eight binding and tightened to achieve compression, thereby fixing it to the slider 1-9.

[0012] Furthermore, the two lugs on the fuse assembly 1 are connected to the two lugs of the locking force indicator assembly 4 via a pull rope 2. The two lugs of the locking force indicator assembly 4 are connected to the two lugs of the adjustment assembly 3 via a pull rope 2. The two lugs of the adjustment assembly 3 are connected to the two fuse wires 1-6 loops of the fuse assembly 1 via a pull rope 2. The rope connection unlocking mechanism can be connected according to the pre-tightening force through the adjustment assembly 3. When unlocking is required, the two fuse wires 1-6 are disconnected by energizing the fuse assembly 1, thereby unlocking the rope connection unlocking mechanism.

[0013] Furthermore, the adjustment component 3 includes a threaded adjustment plate 3-1, a light hole adjustment plate 3-2, and an adjustment screw 3-3. The threaded adjustment plate 3-1 is connected to one section of the pull rope 2, and the light hole adjustment plate 3-2 is connected to another section of the pull rope 2. The pull rope 2 is tightened by tightening the adjustment screw 3-3.

[0014] Furthermore, the locking force indicator component 4 includes a threaded baffle 4-1, a clear hole baffle 4-2, a spring 4-3, and two long screws 4-4. The tails of the two long screws 4-4 are connected to the threaded baffle 4-1 by threads, and the heads of the two long screws 4-4 pass through the clear hole of the clear hole baffle 4-2. The two springs 4-3 are respectively hung on the small holes of the clear hole baffle 4-2 and the threaded baffle 4-1. When the adjusting component 3 is working, the two springs 4-3 are pulled to lengthen. The preload of the rope connection unlocking mechanism is known by measuring the relative distance between the threaded baffle 4-1 and the clear hole baffle 4-2.

[0015] Furthermore, the main collection component 5 includes a bracket 5-1, a small spring 5-2, a small locking screw 5-3, a small locking nut 5-4, and an elastic rope 5-5. The bracket 5-1 is connected to the ground device by screws. One end of the elastic rope 5-5 is connected to the fusible component 1, and the other end is connected to the small spring 5-2 and then to the small locking screw 5-3. The small locking screw 5-3 passes through the light hole of the bracket 5-1 and is fixed and locked by the small locking nut 5-4. When unlocking, the fusible component 1 is pulled down by the action of the main collection component 5, thereby achieving orderly collection without hooking onto irregularly shaped objects.

[0016] The present invention has the following beneficial effects:

[0017] First, the rope connection and unlocking mechanism used in this invention for locking irregularly shaped objects has the flexibility of the rope, which can be used to lock irregularly shaped objects and can provide flexible locking support for any object in any form, thus having good spatial adaptability.

[0018] Secondly, the rope connection unlocking mechanism for locking irregularly shaped objects in this invention mainly consists of three ropes, with the pull rope being a Kevlar pull rope. The fusible component connects the pull rope to the locking force pre-tensioning component, the adjusting component, and the fusible component. The adjusting component allows the rope connection unlocking mechanism to be connected under pre-tension. When unlocking is required, the fusible component can be used to unlock the rope connection unlocking mechanism. The overall mechanism is lightweight.

[0019] Third, in this invention, the rope connection unlocking mechanism for locking irregularly shaped objects has an adjustment component that is tightened by tightening the adjustment screw, thereby tightening the rope, which can effectively reduce impact and provide good connection rigidity.

[0020] Fourth, the rope connection and unlocking mechanism used in this invention for locking irregularly shaped objects integrates connection and unlocking functions as well as swinging and separating functions. Attached Figure Description

[0031] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Figure 2 This is a schematic diagram of a rope-connected unlocking mechanism for locking irregularly shaped objects, provided by the present invention. Figure 2 As shown, the rope connection and unlocking mechanism for locking irregularly shaped objects according to the present invention mainly consists of a fusion component 1, a pull rope 2, an adjustment component 3, a locking force indication component 4, and a main body collection component 5, integrating connection and unlocking functions as well as swing and separation functions. This mechanism can provide flexible locking support for any object in any form, and has the advantages of good spatial adaptability, effective weight reduction, effective impact reduction, and good connection rigidity.

[0033] The fuse assembly 1, adjustment assembly 3, and locking force indicator assembly 4 are all connected by pull rope 2. Due to its flexibility, pull rope 2 is suitable for locking irregularly shaped objects, offering excellent spatial adaptability. Specifically, fuse assembly 1 is connected to locking force indicator assembly 4 via pull rope 2, locking force indicator assembly 4 is connected to adjustment assembly 3 via pull rope 2, and adjustment assembly 3 is connected to fuse assembly 1 via pull rope 2. Adjustment assembly 3 enables the connection of the rope-connected unlocking mechanism. When unlocking is required, the rope-connected unlocking mechanism can be unlocked by energizing fuse assembly 1. The main collection assembly 5 is connected via elastic rope 5-5. Fusel assembly 1 is connected to the ground device via main collection assembly 5.

[0034] Figures 3-6 This is a schematic diagram of the fuse assembly structure provided by the present invention. Figure 3 This is a schematic diagram of the overall structure of the fuse assembly. Figure 4 This is a schematic diagram of a partial front view cross-sectional structure of the fuse assembly. Figure 5 This is a partial top view of the fuse assembly. Figure 6 This is a top-view diagram of the wiring of a partial fuse assembly. Figures 3-6 As shown, the fuse assembly 1 includes a support 1-1, a support cover 1-2, a base 1-3, a clamping cover 1-4, a fuse resistor 1-5, a fuse wire 1-6, an adjusting screw 1-7, an adjusting nut 1-8, and a slider 1-9. It mainly realizes the function of locking irregularly shaped objects around them and unlocking them by connecting the fuse assembly 1 with the pull rope 2.

[0035] In the fuse assembly 1, the base 1-3, the clamping cover 1-4, the fuse resistor 1-5, the fuse wire 1-6, the adjusting screw 1-7, the adjusting nut 1-8, and the slider 1-9 constitute the fuse circuit assembly. One fuse assembly 1 contains one support 1-1, two support covers 1-2, and two fuse circuit assemblies, wherein the fuse circuit assemblies are symmetrically arranged on the support 1-1.

[0036] Support 1-1 serves as a load-bearing component for mounting two fuse circuit assemblies. Support cover 1-2 serves as a seal after the above parts are installed. In the fuse circuit assembly, base 1-3 serves as a load-bearing component for mounting clamping cover 1-4, fuse resistor 1-5, fuse wire 1-6, adjusting screw 1-7, adjusting nut 1-8, and slider 1-9.

[0037] Fuse resistor 1-5 is mounted on base 1-3 with screws. Fuse resistor 1-5 consists of two independent resistors, a and b. Resistor a is soldered to the aviation pin interface (a+, a-) via wires (a+, a-), and resistor b is soldered to the aviation pin interface (b+, b-) via wires (b+, b-). The wires and the aviation pin interfaces (a+, a-) and (b+, b-) extend beyond the fuse assembly 1 through support cover 1-2, allowing the resistors to heat up when external power is applied. Fuse wire 1-6 is in tight contact with fuse resistor 1-5, and the heat from fuse resistor 1-5 causes fuse wire 1-6 to melt. Two screws are mounted on slider 1-9. Fuse wire 1-6 is folded in half and mounted on the two screws using a figure-eight binding method. Tightening the screws secures it to slider 1-9, leaving an opening that extends beyond the fuse assembly 1. Figure 2 The fuse resistors 1-5 indicated are for illustrative purposes only. In reality, the fuse point consists of a resistor, a wire, and an aviation pin. Moreover, fuse resistors 1-5 are all redundant and can all be used to unlock the device.

[0038] The base 1-3 has a groove for sliding the slider 1-9, allowing the slider 1-9 to slide within the base 1-3. The adjusting screw 1-7, after being fixed to the slider 1-9 via its thread, passes through the through hole in the base 1-3 and is screwed onto the adjusting nut 1-8. Tightening the adjusting screw 1-7 adjusts the position of the slider 1-9 within the base 1-3, thereby adjusting the position of the fuse wire 1-6. The clamping cover 1-4 serves as a protective cover for the fuse resistor (1-5) and fuse wire 1-6 after installation, preventing dust accumulation.

[0039] Pull rope 2 mainly consists of three sections of rope, which are Kevlar pull ropes. Two lugs on the fuse assembly 1 are connected to two lugs on the locking force indicator assembly 4 via pull rope 2. The two lugs on the locking force indicator assembly 4 are connected to two lugs on the adjusting assembly 3 via pull rope 2. The two lugs on the adjusting assembly 3 are connected to the two fuse wires 1-6 loops on the fuse assembly 1 via pull rope 2. The adjusting assembly 3 allows the rope connection unlocking mechanism to be connected under pre-tension. When unlocking is required, energizing the fuse assembly 1 disconnects the two fuse wires 1-6, thus unlocking the rope connection unlocking mechanism. It is relatively lightweight.

[0040] Figure 7 This is a schematic diagram of the pull rope and adjustment component structure provided by the present invention. Figure 7 As shown, the adjustment assembly 3 includes a threaded adjustment plate 3-1, a smooth hole adjustment plate 3-2, and an adjustment screw 3-3. It mainly achieves the preload requirement by connecting it with the pull rope 2 and adjusting it according to the specified length of the pull rope 2.

[0041] In the adjustment assembly 3, the threaded adjustment plate 3-1 is connected to the pull rope 2, and the aperture adjustment plate 3-2 is connected to the pull rope 2. After the connection is made, the adjustment screw 3-3 is rotated on the threaded adjustment plate 3-1. By tightening the adjustment screw 3-3, the adjustment assembly 3 is tightened, thereby tightening the pull rope 2, which can effectively reduce impact and provide good connection rigidity.

[0042] Figure 8 This is a schematic diagram illustrating the structure of the pull rope and preload provided by the present invention. Figure 8 As shown, the locking force indicator component 4 includes a threaded baffle 4-1, a smooth hole baffle 4-2, a spring 4-3, and a long screw 4-4. It mainly realizes the determination of the preload by measuring the length of the threaded baffle 4-1 and the smooth hole baffle 4-2 after being connected to the pull rope 2, thus providing a basis for adjusting the tightening position of the component 3.

[0043] The locking force indicator component 4 has two long screws 4-4 with threads at their ends, which connect to the threaded baffle 4-1. The heads of the two long screws 4-4 pass through the holes in the aperture baffle 4-2. Two springs 4-3 are respectively hung on the small holes in the aperture baffle 4-2 and the threaded baffle 4-1. When the adjusting component 3 is working, the circumference of the rope tooling mechanism becomes shorter, pulling the two springs 4-3 to become longer. The relative position of the combination of long screws 4-4 and threaded baffle 4-1 with the aperture baffle 4-2 changes. The relationship between the tension and length of the two springs 4-3 is calibrated beforehand using a tension testing machine. Then, by measuring the relative distance between the threaded baffle 4-1 and the aperture baffle 4-2, the preload of the rope tooling mechanism can be known in real time.

[0044] Figures 9-10 This is a schematic diagram of the main collection component structure provided by the present invention. Figure 9 This is a schematic diagram of the overall structure of the main collection component provided by the present invention. Figure 10 This is a partial structural diagram of the main collecting component provided by the present invention. The main collecting component 5, when unlocked, uses the pull rope 2 to hold the collected components, preventing them from drifting freely and disorderly. Figure 5 As shown, the main collection assembly 5 includes a bracket 5-1, a small spring 5-2, a small locking screw 5-3, a small locking nut 5-4, and an elastic rope 5-5. The main collection assembly 5 is directly connected to the fusible component 1 and the ground device to achieve tension. The main collection assembly 5 includes a bracket 5-1, a small spring 5-2, a small locking screw 5-3, a small locking nut 5-4, and an elastic rope 5-5. The elastic rope 5-5 is an elastic rope.

[0045] In the main collection assembly 5, the bracket 5-1 is connected to the ground device via screws. The elastic rope 5-5 is connected to the fusible component 1. After the elastic rope 5-5 is connected to the small spring 5-2, it is connected to the small locking screw 5-3. Then, the small locking screw 5-3 passes through the light hole of the bracket 5-1 and is fixed and locked by the small locking nut 5-4. When unlocking, the fusible component 1 is pulled downward by the main collection assembly 5, pulling the rope-tied tooling mechanism downward while ensuring the free sliding of the rope. This allows the rope to be collected in an orderly manner during the collection process without getting hooked on irregularly shaped objects.

[0046] The following describes the installation process of the rope connection unlocking mechanism for locking irregularly shaped objects according to the present invention:

[0047] First, install the fuse assembly 1. The two lugs on the fuse assembly 1 are connected to the two lugs of the locking force indicator assembly 4 via a pull rope 2.

[0048] Next, the locking force prediction component 4 is installed. The two lugs of the locking force prediction component 4 are connected to the two lugs of the adjustment component 3 through a pull rope 2. The tails of the two long screws 4-4 in the locking force prediction component 4 are threaded and connected to the threaded baffle 4-1 through the threads. The heads of the two long screws 4-4 pass through the light hole of the light hole baffle 4-2. The two springs 4-3 are respectively hung on the small holes of the light hole baffle 4-2 and the threaded baffle 4-1.

[0049] Next, the adjustment component 3 is installed. The two lugs of the adjustment component 3 are connected to the two fuse wires 1-6 loops of the fuse component 1 via a pull rope 2. The threaded adjustment plate 3-1 in the adjustment component 3 is connected to the pull rope 2, and the aperture adjustment plate 3-2 is connected to the pull rope 2. After the connection is completed, the threaded adjustment plate 3-1 is rotated by the adjustment screw 3-3, and the adjustment component 3 is tightened by tightening the adjustment screw 3-3, thereby tightening the pull rope 2.

[0050] Finally, the main collection component 5 is installed. The elastic rope 5-5 is connected to the fusible component 1. After the elastic rope 5-5 is connected to the small spring 5-2, it is connected to the small locking screw 5-3. Then, the small locking screw 5-3 passes through the light hole of the bracket 5-1 and is fixed and locked through the small locking nut 5-4.

[0051] When unlocking, the fuse wires 1-6 of the fuse component 1 melt and the fuse component 1 is pulled down by the main collection component 5, which pulls the rope tooling mechanism down while ensuring the free sliding of the rope, so that the rope is collected in an orderly manner during the collection process and does not get hooked on irregularly shaped objects.

However, these embodiments are only used to illustrate the present invention more clearly and are not intended to limit the present invention. Any simple modifications, equivalent transformations, or other conceivable changes made by those skilled in the art without departing from the scope of the technical solution of the present invention and based on the technical essence of the present invention shall fall within the scope of the technical solution of the present invention.
