Technical Field

[0001] The present invention relates to the field of aviation and aerospace related technologies, and in particular to a non-explosive device locking and releasing device. Background Art

[0002] The connection and release of payloads and vehicles are widely used, such as the stages of multi-stage rockets, satellites and launch vehicles, satellites and spacecraft, solar wings and spacecraft, unfolded antennas and spacecraft, etc. At present, the methods used are to connect and release based on pyrotechnic devices. Common pyrotechnic connection and release devices include compression seats based on explosive bolts, wrapping belts based on explosive bolts or pyrotechnic cutters, compression seats based on pyrotechnic separation nuts, compression seats based on pyrotechnic cutters, etc. The common feature of these compression and release devices is that the bearing connection force is large. In order to ensure the connection stiffness, the connection force often reaches thousands or even tens of thousands of N. The pyrotechnics as the main components themselves need to be destroyed, so the huge explosive impact force of gunpowder must be used to unlock. This method is one-time use, resulting in high cost, and the explosive impact force is used to unlock, which is easy to cause damage to the spacecraft. In addition, the device based on pyrotechnics has many parts and complex assembly. The pyrotechnics are expensive and cannot be reused, so that the ground test can only be replaced with a new device after each use, which is not conducive to the development of commercial aerospace.

[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0045] like Figures 1 to 12 As shown, a non-explosive locking and releasing device of the present embodiment comprises a load connection mechanism 1, a locking base 2, a pin puller 3, a clamping rod 4, a fastening member 5, an unlocking slider 6 and an unlocking spring 61, wherein the upper end of the clamping rod 4 is connected to the load connection mechanism 1, the lower end of the clamping rod 4 is located in the locking base 2, a guide support is provided in the locking base 2, the upper end of the unlocking spring 61 is connected to the guide support, the lower end of the unlocking spring 61 is connected to the unlocking slider 6, and the unlocking slider 6 is assembled at the lower part of the guide support so as to be able to slide up and down;

[0046] The locking base 2 is further provided with two groups of fastening members 5 symmetrically arranged on both sides of the guide support member, the middle part of the fastening members 5 is hinged to the locking base 2, the lower ends of the two fastening members 5 are provided with rollers 51 rolling contact with the guide inclined surfaces 65 on both sides of the unlocking slider 6, and the upper ends of the fastening members 5 are provided with a clamping section 52 adapted to be clamped with the pressing rod 4; the pin puller 3 is installed on the side wall of the locking base 2 and can realize the clamping and releasing of the unlocking slider 6;

[0047] When in the locked state, the pin puller 3 clamps the unlocking slider 6, the upper ends of the two fastening members 5 are closed and the clamping rod 4 is clamped and positioned through the clamping section 52; when in the unlocked state, the pin puller 3 releases the unlocking slider 6, the unlocking slider 6 moves downward along the rollers 51 at the lower ends of the two fastening members 5, the upper ends of the two fastening members 5 open and release the clamping position with the clamping rod 4.

[0048] Optionally, the pin puller 3 of this embodiment may be a memory alloy pin puller, an electromagnetic pin puller, etc. The upper end of the pressing rod 4 passes through the load connection mechanism 1 and is locked and fixed by a locking nut 42 .

[0049] like Figure 6 , Figure 7 , Fig.11 and Fig.12 As shown, a preferred solution of this embodiment is that the included angles of the guide inclined surfaces 65 on both sides of the unlocking slider 6 and the horizontal plane are the same.

[0050] Optionally, the unlocking slider 6 is a triangular block, and the two inclined surfaces of the triangular block are guide inclined surfaces 65. The triangular block has a compact structure, is easy to manufacture, and is also convenient for rolling contact with the rollers at the lower ends of the two fastening members to unlock or lock. The triangular block is an isosceles triangle block.

[0051] Further preferably, the angle between the guide slope 65 and the horizontal plane is not less than 60°. The larger the angle between the guide slope 65 and the horizontal plane, the smaller the unlocking force, that is, the smaller the force required by the pin puller. However, due to the effective space of the rocket, the entire locking and releasing device cannot be too high, so the angle between the guide slope and the horizontal plane can be preferably 60° to 90°.

[0052] like Figure 4 , Figure 6 , Fig. 9 and Fig.11 As shown, an optional solution of this embodiment is that a vertically arranged guide hole 62 is provided at the middle position of the top of the unlocking slider 6, and the lower part of the guide support is slidably inserted in the guide hole 62. A limiting hole 63 is also provided on the unlocking slider 6, and the central axis of the limiting hole 63 is parallel to the central axis of the guide hole 62, and the side wall of the limiting hole 63 is connected to the side wall of the guide hole 62; the lower part of the guide support is adapted to be slidably inserted in the limiting hole 63 and the guide hole 62. By providing the limiting hole, the lower part of the guide support is prevented from rotating in the guide hole. The guide hole and the limiting hole cooperate to form a spline-like hole structure, and the lower part of the guide support is also set to a spline-like structure.

[0053] like Figure 4 and Fig. 9 As shown, the unlocking slider 6 of this embodiment also has a connecting surface, which is located between the two guiding inclined surfaces 65. A boss 66 is provided on the connecting surface, and the boss 66 is arranged opposite to the pin puller 3 and is used for adapting and engaging with the pin puller 3. The boss is provided to facilitate the adapting and engaging with the pin puller.

[0054] like Figure 6 , Figure 7 , Fig.11 and Fig.12 As shown, a limiting step 41 is provided on the circumferential side of the lower end of the clamping rod 4 of this embodiment, and the step surface of the limiting step 41 is arranged to be gradually inclined downward from the inside to the outside, and the lower surface of the clamping section 52 is adapted to be clamped with the step surface of the limiting step 41. The fastening member is used to clamp and position the clamping rod, and the step surface of the limiting step is arranged to be gradually inclined downward from the inside to the outside, which successfully reduces the large clamping force, so that the pin pulling force required by the pin puller is very small, and the unlocking is not only unlocked by the tension of the unlocking spring when unlocking and releasing.

[0055] Specifically, a limiting step 41 may be provided on opposite sides of the lower end of the pressing rod 4, so that the lower end of the pressing rod forms a "⊥"-shaped block structure.

[0056] like Figure 7 and Fig.12As shown, the lower end of the fastening member 5 of this embodiment is tightened by a tension spring 53; in the locked state, the tension spring 53 is in a stretched state. By providing a tension spring, it is convenient for the two fastening members to be unlocked.

[0057] like Figure 6 , Figure 7 , Fig. 9 , Fig.11 and Fig.12 As shown, the upper end of the locking base 2 of this embodiment is an open structure, and the lower end of the load connection mechanism 1 is adapted to be disposed in the open structure and the peripheral side wall abuts against the inner side wall of the open structure. Since there is surface contact between the load connection mechanism and the locking base, the offset angle is very small after unlocking and separation.

[0058] like Figure 6 , Figure 7 , Fig. 9 , Fig.11 and Fig.12 As shown, the lower end of the pressing rod 4 is located above the guide support. The unlocking slider 6 is provided with an annular assembly groove 64, which is arranged around the lower circumference of the guide support, and the unlocking spring 61 is located in the assembly groove 64. The middle parts of the two fastening members are hinged to the locking base 2 through the rotating shaft 54, and the two rotating shafts 54 are arranged in parallel, and the rotating shaft 54 ​​can be installed on the inner side wall of the locking base 2.

[0059] like Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.11 and Fig.12 As shown, the guide support member includes a crossbeam 7 and a vertical guide bar 71, the two ends of the crossbeam 7 are fixedly connected to the opposite side walls of the locking base 2, the upper end of the vertical guide bar 71 is vertically fixedly connected to the middle position of the bottom wall of the crossbeam 7, the unlocking slider 6 can be mounted on the vertical guide bar 71 to slide up and down, and the upper end of the unlocking spring 61 is connected to the bottom wall of the crossbeam 7. By providing the crossbeam and the vertical guide bar, the installation of the fastening member is convenient, and the connection between the unlocking spring and the unlocking slider is convenient.

[0060] like Figure 6 and Figure 7 As shown, the two fastening members 5 of this embodiment are arranged on both sides of the cross beam 7 and the vertical guide bar 71, respectively, and the rotating shaft 54 ​​of the fastening member 5 is located at an upper position on one side of the cross beam 7. The fastening member is in a 7-shaped structure as a whole. The peripheral side of the roller is exposed from both sides of the lower end of the fastening member, and the fastening member will not interfere when the roller moves on the guide inclined surface of the unlocking slider.

[0061] like Figure 1 to Figure 5As shown, a travel switch 8 is also provided on the outer side wall of the locking base 2 of this embodiment. When the load connection mechanism 1 is locked on the locking base 2 by the pressing rod, the lower surface of the load connection mechanism 1 presses the travel switch 8, and the travel switch 8 is in a powered-on state. When the pressing rod is unlocked by the fastening member, the load connection mechanism 1 no longer presses the travel switch 8, and the travel switch 8 is in a powered-off state. The locking or unlocking state of the load connection mechanism can be timely understood by the power on and off of the travel switch.

[0062] Specifically, the load connection mechanism 1 of this embodiment may adopt a load connection flange.

[0063] The non-explosive locking and releasing device of this embodiment converts rotational motion into horizontal motion, has a compact structure, and is easy to assemble. The locking base can be fixedly connected to the lower fixing plate or the fixed load by screws, and the upper load or other objects (including the satellite body or other loads) can be fixedly connected to the load connection flange by screws. The pin of the pin puller blocks the lower surface of the unlocking slider boss, wherein the unlocking spring is in a compressed state and the tension spring is in a stretched state. Since the unlocking slider blocks the movement of the two fastening members, the limiting step of the "⊥"-shaped block at the lower end of the clamping rod and the clamping surface of the clamping section of the two fastening members are pressed against each other. The clamping rod presses the load connection flange and the locking base through the clamping nut. The fastening member is hinged to the roller so that the roller and the guide inclined surface of the unlocking slider contact each other. Because the contact between the roller and the unlocking slider is an acute angle contact of the inclined surface, the downward force of the entire unlocking slider is several times smaller than the clamping force of the fastening member and the clamping rod, so that the pin pulling force required by the pin puller is greatly smaller, so that the entire mechanism is in a compressed state. After the pin of the pin puller is pulled out by powering on or other means, the unlocking slider moves downward under the elastic force of the unlocking spring because there is no pin blocking it. At this time, the fastening piece and the roller rotate around the rotating shaft under the tension of the tension spring, and the roller rolls along the guide slope, so that the upper ends of the two fastening pieces are opened. At the same time, due to the compression of the clamping rod and the locking nut, the clamping rod, the locking nut and the load connection flange are integrated to separate the upper load and the fixed load. There is a small angle between the fastening piece and the clamping rod, so that the fastening piece has an outward unlocking force when unlocking and releasing, so that the unlocking can be done not only by the tension of the tension spring.

[0064] The non-pyrotechnic locking and releasing device of this embodiment adopts a non-pyrotechnic unlocking method, so that the impact during the overall unlocking is much smaller than that of the pyrotechnic unlocking device. In addition, the number of overall structural parts is small, which makes the overall installation and other aspects much simpler. The non-pyrotechnic locking and releasing device of this embodiment has compact and simple parts, which greatly reduces its overall weight and is more friendly to the aerospace field. This embodiment adopts the cooperation of the guide ramp and the roller, and the cooperation of the unlocking slider and the vertical guide bar, so that the entire unlocking method is carried out under the guiding action, and no deflection occurs when unlocking.
