Description

Technical Field

[0001] The utility model relates to the technical field related to aerospace, and in particular to a locking and releasing device for non-explosive products. Background Art

[0002] The connection and release of payloads to launch vehicles is a common problem, for example, between stages of multi-stage rockets, between satellites and launch vehicles, between satellites and spacecraft, between solar panels and spacecraft, and between deployable antennas and spacecraft. Currently, methods for connection and release are based on pyrotechnic devices. Common pyrotechnic connection and release devices include compression mounts based on explosive bolts, straps based on explosive bolts or pyrotechnic cutters, compression mounts based on pyrotechnic release nuts, and compression mounts based on pyrotechnic cutters. These compression and release devices share a common characteristic: they bear high connection forces, often reaching thousands or even tens of thousands of Newtons to ensure connection rigidity. The pyrotechnic device, as a key component, must be destroyed, necessitating the use of the immense explosive force of the explosive charge to unlock the device. This method is single-use, resulting in high costs, and the explosive force used to unlock the device can easily damage the spacecraft. Furthermore, pyrotechnic devices have numerous parts and complex assembly. The pyrotechnic devices are expensive and cannot be reused, forcing ground tests to require replacement of the device after each use, which is detrimental to the development of commercial spaceflight.

[0015] Furthermore, the unlocking slider also has a connecting surface, which is located between the two guiding inclined surfaces. A boss is provided on the connecting surface, which is arranged opposite to the pin puller and is used for adapting and engaging with the pin puller.

[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 device locking and releasing device of this embodiment includes a load connection mechanism 1, a locking base 2, a pin puller 3, a pressing rod 4, a fastening member 5, an unlocking slider 6 and an unlocking spring 61. The upper end of the pressing rod 4 is connected to the load connection mechanism 1, and the lower end of the pressing 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, and the lower end of the unlocking spring 61 is connected to the unlocking slider 6. The unlocking slider 6 is assembled on 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 sets of fastening members 5 symmetrically arranged on both sides of the guide support member. The middle portions of the fastening members 5 are hinged to the locking base 2. The lower ends of the two fastening members 5 are provided with rollers 51 that roll against the guide inclined surfaces 65 on both sides of the unlocking slider 6. The upper ends of the fastening members 5 are provided with engaging sections 52 that are adapted to engage with the pressing rod 4. The pin puller 3 is mounted on the side wall of the locking base 2 and is capable of engaging and releasing 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 are opened and the clamping position with the clamping rod 4 is released.

[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 、 Figure 11 and Figure 12 As shown, a preferred solution of this embodiment is that the angles between 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 serve as guide inclined surfaces 65. The triangular block is compact and 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 no less than 60°. The larger the angle between the guide slope 65 and the horizontal plane, the smaller the unlocking force, i.e., the smaller the force required by the pin puller. However, due to limited space in the rocket, the entire locking and releasing device cannot be too high, so the angle between the guide slope and the horizontal plane is preferably between 60° and 90°.

[0052] like Figure 4 、 Figure 6 、 Figure 9 and Figure 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 member is slidably inserted into 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 member is adapted to be slidably inserted into the limiting hole 63 and the guide hole 62. By providing the limiting hole, the lower part of the guide support member 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 member is also configured as a spline-like structure.

[0053] like Figure 4 and Figure 9 As shown, the unlocking slider 6 of this embodiment further has a connecting surface, which is located between the two guiding inclined surfaces 65. The connecting surface is provided with a boss 66, which is arranged opposite to the pin puller 3 and is used to adapt and engage with the pin puller 3. The provision of the boss facilitates the adaption and engagement with the pin puller.

[0054] like Figure 6 、 Figure 7 、 Figure 11 and Figure 12 As shown, in this embodiment, a limiting step 41 is provided around the lower end of the pressing rod 4. The step surface of the limiting step 41 is arranged to gradually slope downward from the inside outward, and the lower surface of the engaging section 52 is adapted to engage with the step surface of the limiting step 41. The use of a fastener to engage and position the pressing rod, and the gradually downward sloped step surface from the inside out, significantly reduces the significant pressing force, minimizing the pin pulling force required by the pin puller. Furthermore, unlocking does not rely solely on the tension of the unlocking spring.

[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 Figure 12As shown, the lower end of the fastening member 5 of this embodiment is tightened by a tension spring 53. When in the locked state, the tension spring 53 is in a stretched state. By providing the tension spring, the two fastening members can be easily unlocked.

[0057] like Figure 6 、 Figure 7 、 Figure 9 、 Figure 11 and Figure 12 As shown, the upper end of the locking base 2 in this embodiment is an open structure, and the lower end of the load connection mechanism 1 is adapted to be disposed within this open structure, with its peripheral sidewalls abutting against the inner sidewalls of the open structure. Due to the surface-to-surface contact between the load connection mechanism and the locking base, the deflection angle after unlocking and separation is very small.

[0058] like Figure 6 、 Figure 7 、 Figure 9 、 Figure 11 and Figure 12 As shown, the lower end of the pressing rod 4 is located above the guide support. The unlocking slider 6 has an annular mounting groove 64 formed around the lower circumference of the guide support. The unlocking spring 61 is located within the mounting groove 64. The middle portions of the two fastening members are hinged to the locking base 2 via a rotating shaft 54. The two rotating shafts 54 are arranged in parallel and can be mounted on the inner side wall of the locking base 2.

[0059] like Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 11 and Figure 12 As shown, the guide support member includes a crossbeam 7 and a vertical guide bar 71. The 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 is assembled on the vertical guide bar 71 so as to be able to slide up and down. The upper end of the unlocking spring 61 is connected to the bottom wall of the crossbeam 7. The provision of the crossbeam and vertical guide bar facilitates the installation of the fastening member and the connection between the unlocking spring and the unlocking slider.

[0060] like Figure 6 and Figure 7 As shown, the two fastening members 5 of this embodiment are respectively arranged on either side of the crossbeam 7 and the vertical guide bar 71. The rotating shaft 54 of the fastening member 5 is located slightly above one side of the crossbeam 7. The fastening member has an overall 7-shaped structure. The roller's peripheral side is exposed from both sides of the fastening member's lower end, so the fastening member does not interfere with the roller's movement on the guide slope of the unlocking slider.

[0061] like Figures 1 to 5As shown, a travel switch 8 is further provided on the outer side wall of the locking base 2 of this embodiment. When the load connection mechanism 1 is locked to the locking base 2 via the pressing rod, the lower surface of the load connection mechanism 1 presses against the travel switch 8, and the travel switch 8 is energized. When the pressing rod is unlocked by the fastening member, the load connection mechanism 1 no longer presses against the travel switch 8, and the travel switch 8 is de-energized. The on and off switching of the travel switch allows timely monitoring of the locked or unlocked state of the load connection mechanism.

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

[0063] The non-explosive device locking and releasing device of this embodiment converts rotational motion into horizontal motion, features a compact structure, and is easy to assemble. The locking base can be fixedly connected to a lower fixing plate or fixed load via screws, while an upper load or other object (including a satellite body or other load) is fixedly connected to a load connection flange via 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 tensioning spring is in a stretched state. Because the unlocking slider blocks the movement of the two fastening members, the limiting step of the "⊥"-shaped block at the lower end of the pressure rod and the compression surfaces of the engaging sections of the two fastening members are pressed against each other. The pressure rod, via a compression nut, presses the load connection flange against the locking base. The fastening member is hingedly connected to the roller, causing the roller to contact the guide inclined surface of the unlocking slider. Because the roller and the unlocking slider contact at an acute angle, the downward force of the unlocking slider is several times smaller than the compression force of the fastening member and the pressure rod, thereby significantly reducing the pin pulling force required by the pin puller, thereby maintaining the entire mechanism in a compressed state. After the pin of the pin puller is pulled out by applying power or other means, the unlocking slider, free from the obstruction of the pin, moves downward under the elastic force of the unlocking spring. At this time, the fastening member and roller rotate around the axis driven by the tension of the tensioning spring. The roller rolls along the guide slope, causing the upper ends of the two fastening members to open. Simultaneously, due to the compression of the clamping rod and locking nut, the clamping rod, locking nut, and load connection flange are integrated, thereby separating the upper load from the fixed load. The small angle between the fastening member and the clamping rod creates an outward unlocking force on the fastening member during unlocking and release, ensuring that unlocking is not solely dependent on the tension of the tensioning spring.

[0064] The non-pyrotechnic locking and release device of this embodiment utilizes a non-pyrotechnic unlocking method, resulting in a much smaller impact during overall unlocking compared to pyrotechnic unlocking devices. Furthermore, the overall structure has a small number of components, making overall installation much simpler. The non-pyrotechnic locking and release device of this embodiment features compact and simple components, significantly reducing its overall weight and making it more aerospace-friendly. This embodiment utilizes a guide ramp in conjunction with a roller, and an unlocking slider in conjunction with a vertical guide bar, ensuring that the entire unlocking process is guided and prevents deflection during unlocking.
